Hello!

Let's solve:

  • The sum of all the angles of a triangle is ==> 180 degrees


\hookrightarrow \text{In other words: } x + 59+ 84 + x + 51=180

  • Solve the equation to find the value of 'x'


x + 59 + 84 + x + 51= 180\\2x + 194=180\\2x = -14\\x = -7

  • Since m∠A = x + 51, we just need to plug in x's value

m∠A = x + 51 = -7 + 51 = 44

Answer: 44

Hope that helps!
