Answer:
D. 50
Step-by-step explanation:
a = 90° (angle subtended in semicircle)
a + c + 40° = 180° (by angle sum postulate of a triangle)
90° + c + 40° = 180°
c + 130° = 180°
c = 180° - 130°
c = 50°
4y - 1 = 7 / + 1 ;
4y = 8 /÷4 ;
y = 2 ;
This one is a bit trickier but I do believe the answer is B. About 30 ft2 to 40ft2. Let me know if you need any more help!!!
