Plss help me and explaim too​
masya89 [10]

Answer:

a = b = 1

Step-by-step explanation:

The triangles are similar thus ratios of corresponding sides are equal, that is

\frac{10}{2} = \frac{5}{b} ( cross- multiply )

10b = 10 ( divide both sides by 10 )

b = 1

and

\frac{10}{2} = \frac{5}{a} ( cross- multiply )

10a = 10 ( divide both sides by 10 )

a = 1

Thus a = 1 and b = 1
