Question

Can someone help me this please? Problems 3 and 4. Number 3 is the "Find x" and Number 4 is the Yield sigh.

Answer 1

I am gonna take a guest and say 178 for number 3. And for number 4, the answer is 44.

Step-by-step explanation:

For number 3, I added 76 and 102 which equals 178. For number 4, I put n+6+3n-10=180 because its a triangle. Do the math and you get n=44. Correct me if I am wrong; I tried my best.
