^^^This is to help you. Please hurry, You will also get 82 points. Can someone please answer these. Find the missing value in the following right triangles:

Note: use your calculator and round all answers to whole numbers

1. a = 4, b=?, c=10

2. a = ?, b=3, c=12

3. a = 6, b=?, c=14

4. a = 7, b=?, c=12

5. a = ?, b=9, c=10

6. a = 3, b=?, c=6

7. a = ?, b = 11, c = 14

8. a = 10, b = ?, c = 12

9. a = 15, b = ?, c = 25

10.a=? , b=12, c=12

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

could you provide figure.
