Answer:
A
Step-by-step explanation:
The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.
A property of equilateral triangles is the angles are congruent.
The sum of the 3 angles = 180°, hence the measure of each angle is
= 60° → A
The trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is .
We have to determine
Which trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building?.
<h3>Trigonometric identity</h3>Trigonometric Identities are the equalities that involve trigonometry functions and hold true for all the values of variables given in the equation.
Trig ratios help us calculate side lengths and interior angles of right triangles:
