Josh needs to find the measures of the angles on a barn’s trusses. Find the measure of ∠ABC if ∠ABD is a right angle and ∠CBD is 60°. Write and solve a subtraction equation.

• ∠ABC = 90°

• ∠ABC = 45°

• ∠ABC = 60°

• ∠ABC = 30°

Josh needs to find the measures of the angles on a barn’s trusses. Find the measure of ∠BEF if ∠BED is 85° and ∠DEF is 60°. Write and solve an addition equation.

• ∠BEF = ∠BED - ∠DEF = 85° - 60° = 25°

• ∠BEF = ∠BED + ∠DEF = 85° + 60° = 145°

• ∠BEF = ∠BED × ∠DEF = 85° × 60° = 5100°

• ∠BEF = ∠BED ÷ ∠DEF = 85° ÷ 60° ≈ 1.42°
