What is the measure of arc XY in the diagram below?

30 = XY

Step-by-step explanation:

Angle Formed by Two Secants= 1/2(difference of Intercepted Arcs)

41 = 1/2 ( 112 - XY)

Multiply each side by 2

2*41 = 2*  1/2 ( 112 - XY)

82 = 112 - XY

Subtract 112 from each side

82 - 112 = -XY

-30 = -XY

Multiply by -1

30 = XY

the answer is n

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
