Examine the diagram. A triangle has angles A, 60 degrees, 55 degrees. A line is at the top of the triangle and forms angles B, C, and 65 degrees. Angle C is opposite to angle with measure 60 degrees.

The diagram shows parallel lines cut by two transversal lines creating a triangle. Which statement can be made from the diagram?
mAngleB + mAngleC + 55° = 180°
mAngleA + 60° + 55° = 180°
mAngleC = 55°
mAngleA = 55°

Step-by-step explanation:

As two angles of the triangle are 60° and 55°, the measure of ∠A is:

So the angles C and B measure 60° and 55°.

∠C is opposite to 60°, so is 60° as well, therefore m∠B = 55°

Statements:

mAngleB + mAngleC + 55° = 180°

mAngleA + 60° + 55° = 180°

mAngleC = 55°

mAngleA = 55°

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.
