Work out the size of angle x.

First: 105

Second: 65

Third: 133

Fourth: 129

Fifth: 60

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

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

40 x 50 = 2000
