Answer:
x=58
Step-by-step explanation: Since there is a right angle, you add 22 and 10 and get 32. then you subtract from 90, because 90 degrees is what a right angle measures so you should get 58
Answer: The correct answer is D, y = 40
Step-by-step explanation: The first thing to note is the rule stating that sum of angles in a triangle equals 180 degrees. We have been given three angles which are, 2y, y+ 10 and 50.
If the sum of the angles in a triangle equals 180, then
2y + (y + 10) + 50 = 180
2y + y + 10 + 50 = 180
3y + 60 = 180
Subtract 60 from both sides of the equation
3y = 120
Divide both sides of the equation by 3
y = 40.
I believe so because on ratios have : not / or .
