Answer:
13
Step-by-step explanation:
it's a 5,12,13 triangle
and we can find the sides by Pythagorean theorem:
a^2 + b^2 = root of c
25 + 144 = 169
root of 169 = 13
y=40⁰
x=35⁰
Step-by-step explanation:
y⁰=40⁰ (because they are vertically opposite.)
2 of the triangles are isosceles triangle, in isosceles triangle the 2 bottom angles are the same.
The sum of a triangle is 180⁰,
180⁰=2x+2x+40⁰
180⁰=4x+40⁰
180-40=4x
140⁰=4x
140/4=x
x=35⁰
To check your answer,
2(35)+2(35)+40=180⁰
