Answer:
20° and 90°
Step-by-step explanation:
Let 2x = measure of 1st angle
then 9x = measure of 2nd angle
The sum of the measures of the angles of a quad is 360
200 + 50 + 2x + 9x = 360
250 + 11x = 360
11x = 110
x = 10
2x = 20°
9x = 90°
Answer:
60 degrees
Step-by-step explanation:
Hello! The side lengths of this triangle are all the same, so this is an equilateral triangle. These types of triangles have equal angles. A triangle equals 180 degrees so divide that by three. Each angle in this triangle is 60 degrees. Hope this helps :)
Answer:
∠HDC ≅ ∠HDE, AB ≅ BC, HC ≅ HE
Step-by-step explanation:
yup
I think the answer is 384 in^3
Step-by-step explanation:
J = 2b
M = J + 7
M = 21
J = 21 - 7
J = 14
B = 7
<em>Equation:</em>
If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.
