Answer:
x=20
Step-by-step explanation:
Well we know the right angle is 90 so...
And we also know that all the angle of a triangle add up to 180°.
Knowing this you can subtract 40° and 90°, this gives you 50°...
Then you can substitute 20° for x and then it will be 2(20°)+10°
Simplify and get 40°+10°
This equals 50° degrees
You then add that all up and you get 180°, this mean the answer is correct!
Hope this helps!
All the love, Ya boi Fraser :)
