Answer:

45°

Step-by-step explanation:

Angles in a triangle add to 180 degrees, so

2x - 12 + 2x + 17 + 9x - 7 = 180
13x - 2 = 180
13x = 182
x = 14

So, the measure of angle X is 2(14)+17=45°

Answer:

A = 437 mm²

Step-by-step explanation:

The general formula for the area of a triangle:

A = $\frac{1}{2}bh$ , where 'b' is the measure of the base and 'h' is the measure of the height

Given the dimensions of the triangle in the picture:

A = $\frac{1}{2}(38)(23)$ = 437 mm²
