640. the answer would be 640
The angle subtended by a diameter is always right. That's Thales' Theorem, one of the first in geometry. We conclude y=90°.
The angle subtended by an arc is half the arc length, so z=50°.
The angles in a triangle add to 180°, so x = 180° - y - z = 40°.
Answer: x=40°, y=90°, z=50°
Answer:
No, If there equivalent they don't have to be equal. And if they are equal then don't have to be equivalent
Step-by-step explanation:
Hopes this helps.
7x +2x+27 = 180
9x +27 = 180
-27 -27
9x = 153
÷9. ÷9
x = 17
