Yes. You did it right. Most of the angles are corresponding, and once you found the measure of x, you could use the corresponding angles postulate.

Cos(x) = 2.3 how do I find x?
mote1985 [20]
I don't think you can find x in this case. Cosine can only go as low as -1 and as high as 1. Since 2.3 is more than 1, the answer does not exist

Use the Distance Formula to find the distance between each pair of points. Round to the nearest tenth if necessary.
Eduardwww [97]
3. Sqrt of 40

4. Sqrt of 148


Distance formula is sqrt of (x-x1)^2+(y-y1)^2

So (-4-2)^2+ (3-5)^2

(-6)^2+(-2)^2

36+4

Sqrt of 40

Do the same process for 4!

Ps don’t forget to keep the square root

What is the length of b
oksian1 [2.3K]

Answer:

b = 24

Step-by-step explanation:

<u>Concepts</u>

The Pythagorean Theorem states that the sum of the squares of the two other sides on a right triangle is equal to hypotenuse (longest side) squared. It can be represented by the equation a^2+b^2=c^2. We can also use this formula to solve for the other two legs in the right triangle.

<u>Application</u>

In this case, we're asked to find the length of b in the right triangle, given c as 26 and a as 10. Now, we just apply the formula and solve for b.

<u>Solution</u>

Step 1: Set up equation and simplify.

  • 10^2+b^2=26^2
  • 100+b^2=676

Step 2: Subtract 100 from both sides.

  • 100+b^2-100=676-100
  • b^2=576

Step 3: Take square root of both sides.

  • \sqrt{b^2} =\sqrt{576}
  • b=24

Therefore, b = 24.
