W
→E
O
complementary angles
both acute angles
supplementary angles
O
both obtuse angles

b

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

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.
