Step-by-step explanation:
Im not sure ut it looks like 3x over 3x would cancel eachother out.
H^2=x^2+y^2
9^2=4^2+x^2
81=16+x^2
x^2=65
x=8.1cm
Combine like terms (5y and -y= 4y) and the simplest form would be 4y+7
Answer:
(x+1)+(3x+1)+(2x+4)=180 (sum od all sode of a triangle is 180)
x+1+3x+1+2x+4=180
6x+6=180
6x=180-6
x=174/6
x=66
