Answer:
The proof is given below.
Step-by-step explanation:
Given m∠AEB = 45° and ∠AEC is a right angle. we have to prove that EB divides ∠AEC into two congruent angles, it is the angle bisector.
Given ∠AEC=90° (Given)
∠AEC=∠AEB+∠BEC
⇒ 90° = 45° +∠BEC (Substitution Property)
By subtraction property of equality
⇒ ∠BEC = 90° - 45° = 45°
Hence, both angles becomes equal gives ∠AEB≅∠BEC
Since EB divides ∠AEC into two congruent angles, ∴ EB is the angle bisector.
Answer:
The value of θ is 20.105°
Step-by-step explanation:
Consider the provided information.
A force of F pounds is required to pull an object weighing W pounds up a ramp inclined at θ degrees from the horizontal.
Sine of angle is force over weight.
Substitute F = 5500 pounds and W = 16,000 pounds in above formula.
Hence, the value of θ is 20.105°
