What is x for Unknown angle problems with algebra?

yulyashka [42]

The value of x=20

Step-by-step explanation:

We need to find the value of x

We are given a right angle which is equal to 90°

So, all three angles must sum to 90°

Our equation will be:

$x+2x+(x+10)=90$

Solving and finding value of x

$x+2x+x+10=90\\4x=90-10\\4x=80\\x=80/4\\x=20$

So, the value of x=20

The measure of ∠FHJ is 60°. The measure of ∠FGH is 28°. What is the measure of ∠HFG?

Hatshy [7]

Given
∠FHJ = 60°
∠FGH = 28°

∠FHG = 180 - ∠FHJ
∠FHG = 180 - 60
∠FHG = 120

∠HFG = 180 - (28 + 120)
∠HFG = 180 - 148
∠HFG = 32
