Simplify both sides of the equation then isolate the variable
x=
Substituting a, ( y ) for the given value, which is 8, we proceed to say that:
8y - 4, would be 8 (8) - 4,
which would be 64 - 4 = 60
The answer is: 60
Answer: A should be the answer hope this hopes
Step-by-step explanation:
180 - 90 = 90.
x + 2x = 90
3x = 90
x = 30
One acute angle is 30, the other is 60.
area square: 9in×9in = 81in
area triangle: [9in×(13in-9in)]/2
= (9in×4in)/2
=36in/2
=18in
green area: 81in+ 18in= 99in
