Answer:

The answer to your question is   b = 42

Step-by-step explanation:

Data

hypotenuse = 70

leg 1 = 56

Process

1.- To solve this problem use the Pythagorean theorem.

             c² = a² + b²

c = hypotenuse

a = 56

b = x

2.- Solve for b

              b² = c² - a²

3.- Substitution

              b² = 70² - 56²

4.- Simplification

               b² = 4900 - 3136

               b² = 1764

5.- Result

               b = 42

Point A is (5, 7).
spin [16.1K]

The coordinate of point B is at (29, -15): Option C is correct.

The formula for calculating the midpoint of two points is expressed as:

M(x, y) = {\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}}

Given the coordinate points

A is (5, 7).

B is (x, y).

M is (17, -4)

Substituting into the formula to get x and y

17 = 5+x/2

5+x = 34

x = 34 - 5

x = 29

Get the value of y. Similarly;

-4 = 7+y/2

-8 = 7+y

y = -8-7

y = -15

Hence the coordinate of point B is at (29, -15)
