If the measure of angle 2 is 3x and the measure of angle 1 is 5x-12 then what is the measure of angle 9?

The measure of angle 9 is 108°.

Step-by-step explanation:

We are told that the measure of angles 3,4, 11, 12 are 67, 113, 67, 113 respectively, this means that the lines p and q are parallel.

Further, this means

angle 1  = angle 9 ,

angle 2 = angle 10.

We are also told that

Since angles 1 and 2 are supplementary, they add up to 180°:

so we have

With this value of x we find the numerical value of angle 1 :

since angle 1 = angle 9

answer: slight chance that it will happen

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.
