Question

In the triangle, find x, y, u, v ​

Answer 1

• x = 9
• y = 12
• u = 24
• v = 32

Explanation:

Each of the triangles is similar, so we have ...

3/5 = (3+x)/20

x = 20(3/5) -3

x = 9

__

4/5 = (4+y)/20

y = 20(4/5) -4

y = 12

__

3/5 = (3 + x + u)/60

u = 60(3/5) -3 -9

u = 24

__

4/5 = (4 +y +v)/60

v = 60(4/5) -4 -12

v = 32
