Answer:
∠ 4 = 80°
Step-by-step explanation:
∠ 5 and 100° are vertical angles and are congruent , so
∠ 5 = 100°
∠ 4 and ∠ 5 are same- side interior angles and sum to 180° , that is
∠ 4 + ∠ 5 = 180°
∠ 4 + 100° = 180° ( subtract 100° from both sides )
∠ 4 = 80°
Answer:
We conclude that:

Step-by-step explanation:
Given the expression

Rewrite

,
Therefore, we conclude that:

Answer:
20.49 feet to the nearest hundredth.
Step-by-step explanation:
Using the Pythagoras Theorem:
38^2 = h^2 + 32^2
h^2 = 38^2 - 32^2
h^2 = 420
h = √420
h = 20.494 m.
