Base Angles of Isosceles Triangle given Vertex Angle Solution

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

FIRST Step Consider the formula

∠ Base = \frac{π - ∠ Vertex}{2}

Next Step Substitute values of Variables

∴

∠ Base = \frac{π - 40°}{2}

Next Step Substitute values of Constants

∴

∠ Base = \frac{3.1416 - 40°}{2}

Next Step Convert Units

∴

∠ Base = \frac{3.1416 - 0.6981rad}{2}

Next Step Prepare to Evaluate

∴

∠ Base = \frac{3.1416 - 0.6981}{2}

Next Step Evaluate

∴

∠ Base = 1.2217304763961rad

Next Step Convert to Output's Unit

∴

∠ Base = 70.0000000000169°

LAST Step Rounding Answer

∴

∠ Base = 70°
