I don't know if its a right triangle and we are trying to find the length of the hypotenuse
but if it is, use Pythagorean Theory
c² = √a² + b²
c² = √12² + 5²
c² = √144 + 25
c² = √169
c=13
T= -9 :) , because negative divided by a negative is a positive!
5x-30+5x=180 due to RS and TS being congruent,
10x-30=180
10x=210
x=21

.75
Step-by-step explanation:
I know this because 4 quarts = a gallon so if you do 3/4 of a gallon you get .75
