Answer:

1

Step-by-step explanation:

Identities to be remembered :

<u><em>sin θ = cos (90 - θ)</em></u> or <u><em>cos θ = sin (90 - θ)</em></u>

<u><em>sin² θ + cos² θ = 1</em></u>

<u><em /></u>

=============================================================

Solving :

⇒ cos 50° × sin 40° + sin 50° cos 40°

⇒ cos 50° cos (90 - 40)° + sin 50° sin (90 - 40)°

⇒ cos² 50° + sin² 50°

⇒ 1

Need help (problem and directions in the image):
Alex

Triangle ABC is congruent to triangle CDE using the side - angle - side congruence theorem. The sink hole is 52.2 ft and the Perimeter of ABC is 172.2 ft

<h3>What are congruent triangles?</h3>

Two triangles are said to be congruent if they have the same shape and their corresponding sides are congruent.

In the image shown:

AC = CE, BC = ED and they have the same angle (opposite angles are congruent).

Hence:

Triangle ABC is congruent to triangle CDE using the side - angle - side congruence theorem.

AB = DE = 52.2 ft

Perimeter of ABC = AB + BC + AC = 50 + 70 + 52.2 = 172.2 ft
