Answer:
I think that the answer is D (13,20)
Answer:
X=
Y=
Step-by-step explanation:
The first one is 45-45-90 right angled isosceles triangle.
The length of the hypotenuse ie.X can be found with the help of Pythagoras Theorem.

where a and b are the remaining sides of the triangle,

X=
In the second triangle we have to apply trigonometry,
cos θ=
cos 30°=
=
Thus, Y=
inches
