find the value of x HELP​

Answer 1

Answer:

PLZ MARK AS BRAINLIST

Step-by-step explanation:

We known that it is 90°

3x + x = 90°

Simplifying

3x + x = 90

Combine like terms: 3x + x = 4x

4x = 90

Solving

4x = 90

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '4'.

x = 22.5

Simplifying

x = 22.5

Now we known the value of x

so,

x =22.5

3x = 3 × 22.5

= 67.5

Proof

67.5 + 22.5 =90°

Answer 2

Answer:

x=22.5

Step-by-step explanation:

3x+x= 90

4x=90

x=90/4

x=22.5

3x=3×22.5

3x = 67.5

hence proved that both the angles sum 90 degree........

67.5+ 22.5= 90
