In the figure, is an exterior angle to triangle .
(a) What is the angle measurement of Angle 3. Explain the angle relationship you used.
(b) What is the angle measurement of Angle 4. Explain the angle relationship you used.
(c) What is angle relationship between angles 3 & 4? What is the angle relationship between angles 1, 2, & 3? What do you notice that is similar between the two? What is different?
(d) The combination of which two angles in the triangle equal angle 4? Use your work from Part C to figure out why this is the case, and explain your conclusion.
Answer:
I don't have c but I do have a and b
Step-by-step explanation:
Part A)
Angle 3 is 103° because 77° + ∠3= 180° and ∠3 = 180° - 77° = 103°
Part B)
Angle 4 is 77° because ∠3 + ∠4 = 180° and ∠4 = 180° - 103° = 77°

Answer: Create equations. Top length=Bottom length
Left side = right side.
Combine like terms and rewrite the equations.
Use the new equations to create a system of equations to solve for x and y.
Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.
You should end up with top and bottom lengths of 10. The sides are 9.
Step-by-step explanation:
3x-5 = 18 -2y . Rewrite as 3x + 2y = 23
x+4 = 21 -3y Rewrite as x + 3y = 17
The system of equations is
3x + 2y = 23 and x + 3y = 17 . To solve by substitution, multiply the second equation by -3 It becomes -3x-9y= -51 Add the equations so the x terms cancel. Solve for y
3x + 2y = 23
-3x - 9y = -51
0 -7y = - 28 Divide both sides by -7. y = 4
Substitute 4 for y, solve for x
x + 3(4) = 17
x + 12 = 17 . Subtract 12 from both sides x = 5
Substitute the values of x and y in the expressions
Top: 3x-5 is 3(5) -5 becomes 10
Bottom: 18 -2y is 18 - 2(4) becomes 10
Left: x +4 is (5) + 4 becomes 9
Right: 21 - 3y is 12 -3(4) becomes 9

Roman was studying the life of fish, frogs, and turtles in
Doyle Park. In two hours, he counted 4 more frogs than
turtles. The number of fish he counted was twice the
number of turtles. In total, he counted 68 animals. How
many fish were there?
how many frogs were there? how many turtles were there?
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish

identify the relationship between angles f, b, and a in the above diagram. PLEASE HELP WILL GIVE BRAINLIEST 7TH GRADE MATH
Answer:
Just remember that straight lines are always 180° (a + b = f)
Step-by-step explanation:
Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.
f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:
f+a=180
(switch out with b)
f+b=180
GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.
If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:
a + b = f
The relationship between angles f, b, and a could be as a + b = f.
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.
WE know that the base makes the straight line
f + c = 180
So: f + a = 180
Similarly
f + b = 180
Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees
If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.
120 degree is the same as the sum of a and b, so we could write:
a + b = f
Hence, the relationship between angles f, b, and a could be as a + b = f.

Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?
Answer: 18 pies, 22 cakes
Step-by-step explanation:
Let the number of pies sold be represented by p.
Let the number of cakes be represented by c.
The information in the question can then be represented in an equation as:
p + c = 40 ........ i
10p + 8c = 356 ....... ii
Multiply equation i by 10
Multiply equation ii by 1
10p + 10c = 400 ....... iii
10p + 8c = 356 ....... iv
Subtract iv from iii
2c = 44
c = 44/2
c = 22
22 cakes were sold
Since 40 items were sold, the number of pies sold will be:
= 40 - 22
= 18 pies
