Determine the measure of the indicated angle in the following triangle:
devlian [24]

Answer:

Θ ≈ 58°

Step-by-step explanation:

using the Cosine Rule in the triangle

cosΘ = \frac{80^2+60^2-70^2}{2(80)(60)} = \frac{64000+3600-4900}{9600} = \frac{5100}{9600} = \frac{51}{96} , then

Θ = cos^{-1} ( \frac{51}{96} ) ≈ 58° ( to the nearest degree )

Given: EDF=ABF<br> Name the postulate or theorem you can use to prove ADE=EBA.
Phoenix [80]

The HL (hypotenuse leg) theorem states that any two right triangles that have a  congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

Step-by-step explanation:

AE is congruent to itself.

AB is congruent to DE

<ADE and <EBA are right angles, making them right triangles

Therefore ADE is congruent to EBA by the HL theorem.
