Area of sector = PI x r^2 x (angle/360)
area = PI x 10^2 * (45/360)
area = PI x 100 * 45/360
Area = 25/2x PI
Area = 25PI/2
Answer is D
Answer:
z = 10°
Step-by-step explanation:
Since the two sides are equal, the two base angles have to be equal
That means that 5z and 130 form a straight line and add to 180 degrees
5z+130 = 180
Subtract 130 from each side
5z = 50
Divide by 5
5z/5 = 50/5
z=10
Answer:
C
Step-by-step explanation:
it's an acute angle so it has to less than 90 and 71 just seems like it's too much
