Question

Find the vale of x need help

Answer 1

`x=45`

Explanation:

→a+b+c=180

→Angle a is given to be 90 degrees

→ Also the other to angles are the same length so the same angle

`90+2x=180`

Step 1: Subtract 90 from both sides.

`2x+90-90=180-90`

`2x=90`

Step 3: Divide both sides by 2.

`(2x)/(2) =(90)/(2)`

`x=45`

Answer:

x=45

Answer 2

x=45 degrees

Explanation:

You can see based off of the markings on the 2 sides, that it is an isosceles triangle, so that means the 2 base angles are equal.

so 2x+90=180 degrees

so 2x=90 degrees

x=45
