The measure of Angle D is
degrees.
O=41 degrees
Answers
Answer:
49°
Step-by-step explanation:
O=41° and G=90° (because it is a right angle). The sum of the interior angles of a triangle is 180°. So, add the known angles, 41°+90°=131°. Since the sum of all three angles needs to be 180°, subtract the known angles from the total, 180°-131°=49°, to find the unknown angle.
The angle D in triangle OGD measures 49 degrees.
To find the measure of angle D in triangle OGD, we can use the fact that the sum of the angles in a triangle is always 180 degrees.
Given that angle O is 41 degrees and angle G is 90 degrees, we can substitute these values into the equation:
Angle O + Angle G + Angle D = 180
41 + 90 + Angle D = 180
131 + Angle D = 180
Now, we can solve for angle D by subtracting 131 from both sides:
Angle D = 180 - 131
Angle D = 49
Therefore, angle D in triangle OGD measures 49 degrees.

Write 0.6% as a fraction in simplest form.
Answers
Answer:
[tex]\frac{3}{5}[/tex]
Answer:
3/500
Step-by-step explanation:
Percent means
per hundred.
So we have the following.
0.6%=0.6 per hundred = 0.6/100
We next need to rewrite 0.6/100 so that is doesn't have a decimal in the numerator.
To do this, we multiply it by 10/10, which equals 1.
0.6/100 = 0.6/100 x 10/10 = 6/1000
(Note that we do not try to cancel when doing the multiplication.)
Our answer must be written in simplest form.
This fraction has a denominator of 1000.
So we can simplify it by focusing only on the factors 2 and 5.
In this case, we can divide both the numerator and denominator be 2.
6/1000 = 6 ÷ 2/1000 ÷ 2 = 3/500
We cannot use 2 or 5 to simplify further. So 3/500 is in simplest form.
So the answer is 3/500.
Find the slope of a line with this information, "−12; (4,−5)". Write your answer in slope intercept form.
Answers
Answer:
y = -12x - 43
Step-by-step explanation:
"slope-intercept form" looks like y = mx + b.
We are given m = -12 and a point on the line which is (4, -5).
Substituting 4 for x, -5 for y and -12 for m, we get:
-5 = -12(4) + b. Then b = -43, and the desired equation is y = -12x - 43.
