Please help with #1 and 2 for finding the missing length of the right triangle using the Pythagorean theorem. PLEASE SHOW HOW YOU DID IT...

1- 9 yards

2- 5.4 inches

3- 2.6 feet

Step-by-step explanation:

Pythagorean theorem states a²+b²=c², or, side 1 ² + side 2 ² = the hypotenuse, aka the longest side. In right triangles, the hypotenuse is always diagonal to the right angle.

In problem one, the hypotenuse in 15 yds. In problem two, it is ?. In problem three, it is 9ft.

onto the math.

1-

you are missing a side measurement, so you would set up the equation as

12²+b²=15²

simplify what you have to get

144+b²=225

subtract 144 from both sides to get

b²= 81

the square root of 81 is 9, since 9×9=81

so your answer is

9 yards.

2-

This time, you are missing the hypotenuse.

once again, you should fill in what you know.

2²+5²=c²

simplify what you have to get

4+25=c²

add 4 and 25 to get

29=c²

the square root of 29 is a really long decimal, but since the instructions say to round to the nearest tenth, the answer is

5.4 inches.

3-

Just like in problem one, you are missing a side length.

First, fill in what you know.

6²+b²=9²

simplify it down to get

36+b²=81

take 36 from both sides and you get

b²=45

the square root of 45 to the nearest tenth is your answer of

2.6 feet

b. x- 48 =120

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
