Answer:

Step-by-step explanation:

Set the two unknown numbers to X and Y.

X + Y = 22

2X = 10Y

Rewrite the second equation as: X = 5Y

Now use this in the first equation: 6Y=22

Y = 3.67 [3 2/3]

X = 18.33 [18 1/3]

---------------------------------------

3 2/3 + 18 1/3 = 22, and

2*(18 1/3) = 10*(3 2/3)

Answer:

Question 1

since triangles are similar

angle B = angle D

8x + 16 = 120

x = 13

Question 2

Ttiangles are similar

therefore, sides are in ratio

AB ÷ XY = BC ÷ YZ = AC ÷ XZ

substituting all values we get

BC = 22

BC = 22AC = 16
