The perimeter is 24 inches squared
Answer:
C
Step-by-step explanation:
Angles of a triangle add up to 180 degrees and then we take away the right angle
180-90=90
5x+5x=10x
90/10=9
x=9
Answer:
Step-by-step explanation:
Pythagoras theorem
a^2=b^2+c^2
(x-2)^2=9^2+(x+1)^2
x^2-4x+4=81+x^2+2x+1
Collect like terms
-4x-2x=82-4
-6x=78
x=-13
