Question

Since the triangle below contains an obtuse angle what type of angle must angle x be

Answer 1

Option B) Acute

Explanation:

we know that

if a triangle contains an obtuse angle, then the other two angles must be acute.

Verify

The sum of the interior angles of a triangle must be equal to 180 degrees

in the triangle of the figure

113°+15°+x°=180°

Solve for x

118°+x°=180°

x=180°-118°=62°

62° < 90°

therefore

The angle x is an acute angle
