Answer 1

o find the value of z, we can use the fact that the sum of the angles in a triangle is always 180 degrees.

So, we can set up the equation:

2z + 110 + 3z - 5 = 180

Combine like terms:

5z + 105 = 180

Subtract 105 from both sides:

5z = 75

Divide by 5:

z = 15

Therefore, the value of z is 15.

The closest answer choice is D) 1515.
