Answer:
C. RS=IS
Step-by-step explanation:
To use ASA the side between the two congruent angles must be equal as well. Given one set of congruent angles, we can assume the other congruent angles to be the vertical angles in the middle. In order for ASA to work, the side between those angles must also be congruent.
IF YOUR SOLVING FOR A THE ANSWER WOULD BE A=X+12
IF YOUR SOLVING FOR X IT WOULD BE X=-12+A
Answer:
-17 =s
Step-by-step explanation:
-8s +4 = -7s +21
Add 8s to each side
-8s+8s +4 = -7s+8s +21
4 = s+21
Subtract 21 from each side
4-21 = s+21-21
-17 =s
180=76+4x
180-76=4x
104=4x
104/4=x
26=x
Measurement A= 26
A^2+b^2=c^2 (Pythagoran theorem)
-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft
=> area = length x width = 72 x 30 = 2160 ft^2</span>
