Find x and y 30 points

Vika [28.1K]

Since the two triangles are similar

$\frac{5 + x}{5} = \frac{7 + y}{7} = \frac{10}{8} \\ \implies \frac{5 + x}{5} = \frac{10}{8} \\ \implies x = \frac{50}{8} - 5 = \frac{50 - 40}{8} = \frac{10}{8} = \frac{5}{4} \\ \therefore x = \frac{5}{4}$

Also,

$\\ \frac{7 + y}{7} = \frac{10}{8} \\ \implies y = \frac{70}{8} - 7 = \frac{70 - 56}{8} \\ \therefore y = \frac{14}{8} = \frac{7}{4}$

The diagram shows a parallelogra,. 3x-15, 2x, 2x, 2x+24, work out x

liraira [26]

Answer:

x = 39

Step-by-step explanation:

In a parallelogram the opposite angles are congruent, thus

3x - 15 = 2x + 24 ( subtract 2x from both sides )

x - 15 = 24 ( add 15 to both sides )

x = 39
