Angle R and S are complementary angles If M angle R= (6x-47) and m angle S = (x+4) find m angle S

Answers

Answer:

Step-by-step explanation:

x + 4 + 6x - 47 = 90

7x - 43 = 90

7x = 133

x = 19

S = 19 + 4 = 23

R = 6(19) - 47 = 114 - 47 = 67

An arc of a circle measures 80 degrees and the length of 88pie cm. what is the diameter?

Answers

If 80° ------> 88π cm
Then 360° ------> x cm

So:

x = (88π x 360) ÷ 80
x = 396 π (lenght of the circle)

The relationship of Lenght of circle and its diameter is:

L = d .π

replacing L:
396 π = d.π ----> d = 396 cm <---- here is your answer
