If m∠c=11x+85/3 and x=13 then what type of angle is c please help me with this

GuDViN [60]

Answer:

Acute angle

Step-by-step explanation:

Given that m<C = $\frac{11x + 85}{3}$ , to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.

m<C = $\frac{11x + 85}{3}$

m<C = $\frac{11(13) + 85}{3}$

m<C = $\frac{228}{3}$

m<C = 76°

Acute angles are less than 90°.

m<C is less than 90°, therefore it is an acute angle.
