AB = AC, they are equivalent. Since an isosceles triangle has the congruent angle property, mB = mC cannot be shown until AB=AC.
<h3>What is
Isosceles triangles?</h3>
Generally, Isosceles triangles are those that have two sides that are equal in length and two angles that are also equal in size.
Hence The sides and angles theorem for triangles., and the side AB is equal to the other side AC,
In conclusion, Assuming that the base angles, mB, and mC, are of equal measure, the triangle sides and angles theorem states that segment AC is larger than AB. The bigger angle of a triangle is always opposite to the longer side, according to the theorem.
AB is congruent to AC cannot be proven unless AB=AC then,
m<B = m<C because the isosceles triangle has the congruent angle property

?
Step-by-step explanation:
Answer:
<h2>The answer is 1</h2>
Step-by-step explanation:
First of all transform the expression using trigonometric identities
That's
So we have
Reduce the expression with tan x
We have
Reduce the expression with cos x
That's
Reduce the expression with sin x
We have
We have the final answer as
<h3>1</h3>
