Question

Please help!
I'm having a tuff time figuring this out.

Answer 1

Answer:

x = 17

Step-by-step explanation:

Since the triangles are congruent

<I = <P

3x+4 = 72-x

Add x to each side

3x+4+x = 72-x+x

4x+4 = 72

Subtract 4 from each side

4x+4-4 = 72-4

4x = 68

Divide each side by 4

4x/4 = 68/4

x = 17
