Question

I need help with this

Answer 1

Let's understand some trigonometric concepts about a triangle to answer the question.

Sum of Angles:

The sum of the three angles in any triangle is always 180 degrees. Regardless of the type of triangle (acute, obtuse, or right-angled), the total of its angles will always be 180 degrees.

Knowing this information we can create an equation and solve for x.

`(2x+16)+59+79=180`

`2x+16=42`

`2x=26`

`x=13`

Answer: x = 13
