Answer:

1. a = 4, b = 2√2

Step-by-step explanation:

The right triangle is isosceles, so b is the same length as the marked side:

b = 2√2

The hypotenuse of an isosceles right triangle is √2 times the leg length, so ...

a = (√2)(2√2) = 2·2 = 4

The missing sides are ...

a = 4, b = 2√2

Step-by-step explanation:

Write and solve an equation twice a number is 26

x = unknown number

Equation: 2x = 26

Solve:

2x = 26

/2 /2 <== divide both sides by 2

x = 13

Check your answer:

2x = 26

2(13) = 26

26 = 26

This stament is correct
