Answer:
The first shape is triangle; area of a triangle = 1/2*b*h
= 1/2*7*3
= 1/2*21
= 21/2
= 10.5
The second shape is rectangle; area of rectangle = l*b
= 7*3
= 21
Total area:
10.5+21
= 31.5
Answer:
D) 140°
Step-by-step explanation:
The total number of degrees in a triangle is 180. Since both sides of the triangle are the radius of the circle, the triangle is isosceles. Therefore the two opposite angles are equal. Thus, the central angle is 180° − 2(20°) = 140°.
