Question

2. Find x if the mZFED= 1190, mZIED= x+61, and m/FEI= x + 66, is

Answer 1

x = - 4

Explanation:

∠ FEI and ∠ IED form ∠ FED , that is

∠ FEI + ∠ IED = ∠ FED ( substitute values )

x + 66 + x + 61 = 119

2x + 127 = 119 ( subtract 127 from both sides )

2x = - 8 ( divide both sides by 2 )

x = - 4
