x = 22 degrees

Step-by-step explanation:

Since this is a right angle and both angles added together will equal to 90degrees this means that:

(3x-5) + (x+7) = 90

(first, remove the brackets)

3x-5+x+7 = 90

( add the numbers together and the term x together)

( 3x+x ) + ( -5+7 ) = 90

4x + 2 = 90

(subtract 2 from both sides)

4x = 88

(divide by 4 from both sides)

x = 22

so the measure of x = 22 degrees

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
