Two angels in a triangle add up two 115 degrees what is the size of the third angle
Bogdan [553]
The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle

solve
115+z=180
subtract 115 from boths ides
z=65

answer is third angle=65 degrees

Can anyone help? It’s not 14, I’ll give Brainly + 15 pts
Julli [10]

Short side length = x

Medium side = x + 7

Long side = 5x

Total 49, so

x + x + 7 + 5x = 49

If you combine like terms:

7x + 7 = 49

Subtract 7 from both sides

7x = 42

Divide both sides by 7

x = 6 inches.
