Answer:
x
Step-by-step explanation:
C! 80 + 10 is 90, 90+90 is 180. There are 180 degrees in one triangle
Assuming the figure has identifiable bases and sides, the total surface area is the sum of the areas of those:
... B. Base area + lateral area
Answer:
B. 56°
Step-by-step explanation:
We are given that m∠R is 66° and m∠T is 122°.
We can apply the supplementary rule since ∠S and ∠T are a linear pair. So, we can use ∠T to find ∠S through 180° - 122° = 58°.
Now, we can use ∠R and ∠S to find ∠Q.
66° + 58° = 124°
180° - 124° = 56°
Divide by 3 on both sides:
Square root both sides:
Take away 3 from both sides:
Divide by 2 on both sides:
