What is the measure of x in the triangle below? Round to the nearest degree. The figure is not drawn to scale.

Question

Triangle 12, 18, x°

Inside triangle 38°

X= 67

Answer 1

To find the measure of x, we can use the fact that the sum of the angles in a triangle is 180 degrees.

So, we have:

x + 12 + 18 = 180 (the three angles of the triangle)
x + 30 = 180
x = 150

However, this is not the final answer because we know there is an additional angle inside the triangle that measures 38 degrees. So, we subtract that from the x we found:

x - 38 = 150 - 38
x = 112 degrees

Rounding to the nearest degree, we get:

x ≈ 67 degrees (rounded to the nearest degree).
