Aright triangle has side lengths 7, 24, and 25 as shown below.
use these lengths to find tan b, sin b, and cos b.
tan b
sinb =
lnb
cosb =

see below in bold.

step-by-step explanation:

7 and 24 are the lengths of the 2 legs   and 25 is the length of the hypotenuse.

assuming   angle b is opposite the leg of length 7:

tan b = opposite/ adjacent side = 7/24.

sin b = opposite / hypotenuse = 7/25

cos b = adjacent /hypotenuse = 24/25.

is should be y = 5x

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
