each shape. The shapes are not drawn to scale.​

Answer 1

Answer:

How to find the sides of a right triangle

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)if leg b is unknown, then. b = √(c² - a²)

if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)if leg b is unknown, then. b = √(c² - a²)for hypotenuse c missing, the formula is. c = √(a² + b²)

Answer 2

Answer:

30m

Step-by-step explanation:

1/2 =0.50

7.50 + 4 + 1.50 + 2 + 9(7.50+1.50) + 6(4+2)
