Vertex Angle of Isosceles Triangle given Base Angles Solution

Follow our step by step solution on how to calculate Vertex Angle of Isosceles Triangle given Base Angles?

FIRST Step Consider the formula

∠ Vertex = π - 2 \cdot ∠ Base

Next Step Substitute values of Variables

∴

∠ Vertex = π - 2 \cdot 70°

Next Step Substitute values of Constants

∴

∠ Vertex = 3.1416 - 2 \cdot 70°

Next Step Convert Units

∴

∠ Vertex = 3.1416 - 2 \cdot 1.2217rad

Next Step Prepare to Evaluate

∴

∠ Vertex = 3.1416 - 2 \cdot 1.2217

Next Step Evaluate

∴

∠ Vertex = 0.698131700798193rad

Next Step Convert to Output's Unit

∴

∠ Vertex = 40.000000000034°

LAST Step Rounding Answer

∴

∠ Vertex = 40°
