Answer:
see explanation
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
5x + 20 + 7x - 8 = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Thus
∠ RQP = 10x = 10(14) = 140°
∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )
∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°
∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°
Given radius=15 inches
Perimeter=circumference of circle
Circumference=2 pi r
=pi=22/7 or 3.14
=2*3.14*15=94.2
Rounded off=100

Answer: 45/64
Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.
So here, we have 9 × 5 which is 45 and 8 × 8 which is 64. So now we have 45/64.
The fraction 45/64 is in lowest terms so this is our final answer.
