Answer and Step-by-step explanation:
Since this is a quadrilateral, we know that all the angles will add up to 360 degrees (by definition). We are given that angle A is 90 degrees and that the ratio of A to B is 5 to 3. This means that we can set up a proportion and solve for B:
A/B = 5/3 ⇒ 90/B = 5/3 ⇒ 5B = 270 ⇒ B = 54
So, we know that angle B is 54 degrees.
Now that we know angle B is 54 and A is 90, we can find the sum of the remaining two angles X and Y because A + B + X + Y = 360:
90 + 54 + X + Y = 360
X + Y = 216 degrees
We also know that the ratio of X to Y is 1 to 3, so we can set up another proportion:
X/Y = 1/3 ⇒ Y = 3X
Substitute 3X in for Y in X + Y = 216:
X + 3X = 216
4X = 216
X = 54
Thus, we see that both angles B and X equal 54, so B = X.
Hope this helps!
