Answer:
x = 20°
y = 30°
Explanation:
First, let's try to solve for x. The angle x and the 70° angle are both part of a right angle, which has 90°. Because of this information, we can make an equation:
![x+70=90\\](https://img.qammunity.org/2022/formulas/mathematics/high-school/bs4r0lfcce9midgpx7s5y2x2wmgkydw91t.png)
Let's remove 70 from both sides to solve for x.
![x=20](https://img.qammunity.org/2022/formulas/mathematics/college/kclxpemqgvb461v1a2b4otfn875uvr1nj0.png)
So, now we know the value of x. Let's now solve for y. Now, we know that the three angles (which all have the same value - y) are part of one angle, a right angle. Remember that a right angle has 90°. So, this can be our equation:
![3y=90](https://img.qammunity.org/2022/formulas/mathematics/high-school/44k4fj1unyia0dxennlp3h978zllz5f17t.png)
Let's divide by 3 both sides to solve for x.
![y=30](https://img.qammunity.org/2022/formulas/mathematics/high-school/q84p44o6wssvi49k47rc5smhajr7jkkk18.png)
And now we know the value of both x and y. Hopefully this was helpful - if you have any more questions, let me know! :)
