Answer:
x=5
Step-by-step explanation:
Congruent triangles mean they have the same side lengths, so the equation here is x^2-7=4x-2. Then, solve the quadratic equation:
x^2-7=4x-2
x^2-4x-5=0
(x-5)(x+1)=0
x=5,-1
Since a side of a triangle can't be negative, the answer is 5.

Answer:
1 4 2
Step-by-step explanation:
Answer:
s = 72.5
r = 77.5
Step-by-step explanation:
Make a system of equations:
r = s + 5
r + s = 150
Input r into the second equation:
s + 5 + s = 150
2s + 5 = 150
2s = 145
s = 72.5
Put this back into one equation
r = 72.5 + 5
r = 77.5
