Hey there! :)
Answer:
m∠y = 55°.
Step-by-step explanation:
Begin by solving for x since y and x are supplementary angles.
Recall that all of the angles in a triangle must sum up to 180°. Therefore:
180 - 30 - 25 = 125°.
x = 125°, therefore:
180 - 125 = 55°.
m∠y = 55°.
Answer:
Step-by-step explanation:
Area of shaded region = Area of quadrant - area of triangle
= (1/4)πr² - (1/2)bh

= 7 cm²
Answer:
The answer is B
Step-by-step explanation:
You know this because the congruency statements are the same on both triangles.
