Answer:
X=35
Step-by-step explanation:
Those 2 angles equal each other, meaning they're the same.
Knowing that you put them to equal each other.
2x+15=3x-20
Then you solve it.
20+15=3x-2x
35=1x
X=35
This took a while since I had to do a lil' work.
Answer is C.
Answer: 86.34813
Step-by-step explanation:
l= (square root)r^2 + h^2 = (square root)20^2 + 84^2
Answer:
Step-by-step explanation:
Given
(5x - 3y)² = 0, then
5x - 3y = 0 ( add 3y to both sides )
5x = 3y (divide both sides by 5 )
x = y ( divide both sides by y )
=
Answer:
It is an isosceles triangle.
Step-by-step explanation:
sum of angles of triangle = 180
since it is isosceles two angles will be same. let it be x.
x + x + 22 = 180
2x = 180 - 22
2x = 158
x = 79°
