50

Step-by-step explanation:

Equilateral triangles have angles that all measure the same

180/3 = 60

so all angles measure 60

<c = 60

60 = x+10

Subtract 10 from each side

60-10 = x+10-10

x=50

The answer to your question is   x = 50

Step-by-step explanation:

Data

Equilateral triangle

∠C = x + 10

Process

To solve this problem we must consider these facts about triangles

- The sum of the internal angles in a triangle equals 180°

- All the angles in an equilateral triangle measures the same,

Equations

                    ∠A + ∠B + ∠C = 180°

but

                    ∠C + ∠C + ∠C = 180°

-Simplification

                                    3∠C = 180°

-Substitution

                                3(x + 10) = 180°

-Expand

                                3x + 30 = 180°

-Solve for x

                                3x = 180 - 30

                                3x = 150

                                  x = 150/3

                                  x = 50
