Solve for x round to the nearest tenth if necessary

x ≈ 7.7

Step-by-step explanation:

Using the sine ratio in the right triangle

sin69° = = = ( multiply both sides by x )

x × sin69° = 7.2 ( divide both sides by sin69° )

x = ≈ 7.7 ( to the nearest tenth )

idk

step-by-step explanation:

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.
