Find the angle measures.
Help!!!!
Answers
Answer:
(x-9)°+6x=180°[by linear pair]
7x-9=180°
7x=180°+9
7x=189°
x=189/7
x=27
(x-9)°=27-9=18°
(6x)°=6×27=162°
The angle measures are 18 degrees and 162 degrees.
What is Angle?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
In the given figure ∠1=x-9 and ∠2=6x
The sum of ∠1 and ∠2 is 180 degrees by linear pair.
∠1 +∠2 =180
x-9+6x=180
Add the x variable terms
5x-9=180
Add 9 on both sides
5x=189
Divide both sides by 5
x=27
Now substitute value of x in angle 1 and angle 2.
∠1=x-9=27-9=18 degrees
∠2=6x=6(27)=162 degrees.
Hence, the angle measures are 18 degrees and 162 degrees.

Lorenzo ate 25 of his bag of almonds. His 4 friends ate equal shares of the remaining bag of almonds. Which expression represents the almonds that each friend ate?
Answers
Answer:
(x - 25) / 4
Step-by-step explanation:
In this scenario, we have one unknown variable which is the total of the bag of almonds, therefore we can represent this with the variable x. Since Lorenzo ate 25 of this bag we would need to subtract this from the total of the bag. Then we need to divide the remainder by 4 since each of his friends ate the rest in equal parts. This would leave us with the following expression ...
(x - 25) / 4

The ratio of the measure of the three angles of a triangle is 3:4:8. Find the mesure of the large angle
Answers
Answer:
96°
Step-by-step explanation:
Ratio of angles :
3 : 4 : 8
Sum of angles in a triangle = 180°
The value of the largest angle = angle with the largest ratio
This is the value of the angle with ratio 8
Sum of ratio : (3 + 4 + 8) = 15
Hence,
(8 / 15) * 180°
(8 * 180°) / 15
1440 / 15
= 96°
