Step-by-step explanation:
8x-10=3x+90
=5x=100
=x=20
therefore
B=3(20)+90
150°
The answer is 789 :))) have a great day
34 = 2b+2h
17 = b+h
b = 17-h
30 = b*h
30 = (17-h)h
30 = 17h - h^2
h^2 - 17h + 30 = 0
(h - 15)(h - 2) = 0
h = 2 or h = 15
if h = 2 then b = 30/2 = 15
if h = 15 then b = 30/15 = 2
so one side is 15 long and one side is 2 long
by the way its not a square
132.54in2 Is the answer! ;3 Goodluck.
80+60=140
180-40 = 40
Answer is 40°
As angles in a triangle add up to 360°
