Pls answer for my hw thanks

27.86 cm

Step-by-step explanation:

use a^2+b^2=c^2

plug in 10 to a and 26 to b

so

10^2+26^2=c^2

then simplify

100+676=c^2

776=c^2

then find the square root of 776 which is 27.856... cm

this can be simplified to 27.86 cm

change it to 28 cm if your teacher wants it rounded to the whole number

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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
