Find the missing part for A, Y, Z, and B.

All (3) of the triangles are similar to one another, and they have the 30-60-90 interior-angle pattern. This allows us to establish the following relations.

$a+b=2x\implies x=\dfrac{15}2$

$z=\sqrt3\,x\implies z=\dfrac{15\sqrt3}2$

$\dfrac ax=\dfrac x{a+b}\implies a(a+b)=x^2\implies15a=\dfrac{15^2}{2^2}\implies a=\dfrac{15}4$

$a+b=15\implies b=15-\dfrac{15}4=\dfrac{45}4$

$y=\sqrt3\,a\implies y=\dfrac{15\sqrt3}4$

Find the values of x and y.

lubasha [3.4K]

Answer:

x = 20 degrees and y = 70 degrees

Step-by-step explanation:

The first thing you do is work out the angle next to 180 degrees

180 - 40 = 140

Bottom angles in an isosceles triangle are equal.

180 - 140 = 40

40/2 = 20

so x = 20 degrees

The next thing is right angle - 20 = 70 degrees

Angles in a triangle add up to 180 degrees

70 + 40 = 110

180 - 110 = 70

so y = 70 degrees
