They both are complementary, so their sum would be 90 degrees.
5x-12 + 4x+3 =90
9x - 9 = 90
9x = 99
x = 11

So, angle 1 = 5x-12 = 5(11)-12 = 55-12 = 43
angle 2 = 4x+3 = 4(11)+3 = 44+3 = 47

So, your final answers are: angle 1 = 43 degrees & angle 2 = 47 degrees

Hope this helps!

You'd need to convert feet into inches first. 2 feet is 24 inches. then add the other three inches. Juan's dog is 27 inches tall and Peters dog is 9 inches tall.

your fraction would be 27/9 which simplifies to 3.

Juan's dog is 3 times bigger than Peters!

$-np-80 < 60\qquad\text{change the signs}\\\\np+80$

------------------------------------------------------

$2a-5d=30\qquad\text{subtract 2a from both sides}\\\\-5d=-2a+30\qquad\text{change the signs}\\\\5d=2a-30\qquad\text{divide both sides by 5}\\\\d=0.4a-6$
