I would say B is the correct answer because of the Pythagorean theorem.
a^2 + b^2 = c^2
XY^2 + YZ^2 = ZX^2
12^2 + 16^2 = 20^2
144 + 256 = 400

My best guess is B.

Hope this helps =)

Triangle XYZ is formed by the three squares J, K, and L

So it is a right triangle.

Pythagorean Theorem: a^2 + b^2 = c^2

Answer:

(XY)^2 + (YZ)^2 = (ZX)^2, because 144 + 256 = 400

Solve BCD Round the answer to the nearest hundredth
lesya [120]

Answer:

A

Step-by-step explanation:

The measure of angle D can be found using the Interior Angle Sum of a Triangle.

The angles of a triangle add to 180. This means:

90 + 21 + x = 180.

111 + x = 180

x = 69

The solution is A.

Angle B is smaller than Angle D which means CD will be smaller than BC.

Help someone please!! don’t understand
Citrus2011 [14]
Radical 2 = 1.4 So 1.4 * 6 = 8.4

a^2 + b^2 = c^2

8.4^2 + 8.4^2 = square root of c

70.56 + 70.56 = 141.12 ≈ 141

Then you must find the square root of 141 which is 11.874 ≈ 11.9

Side a = 8.4
Side b = 8.4
Side c = 11.9

Which of these points are on a line that has a slope of -3?
Ira Lisetskai [31]
Simple....

using the formula \frac{ y_{1}- y_{2}  }{ x_{1}- x_{2}  } to find slope....

1.)  (9,2)(4,3)

\frac{2-3}{9-4}= -\frac{1}{5} (No)

2.)  (9,2)(3,4)

\frac{2-4}{9-3} = -\frac{2}{6} =- \frac{1}{3} (No)

3.)  (2,9)(3,4)

\frac{9-4}{2-3} = \frac{5}{-1} =-5 (No)

4.)  (2,9)(4,3)

\frac{9-3}{2-4} = \frac{6}{-2} =-3 (YES!)

Thus, your answer.

I am just completely lost and am unsure of how to approach this problem.
Anastasy [175]

Answer:

68°

Step-by-step explanation:

As BA⊥BD, so ∠ABD = 90°

also, ∠ABD = ∠CBD + ∠ABC

⇒ 90° = 4x + 52° + 8x - 10°

⇒  12x = 48°

⇒  x = 4°

now,

∠CBD = 4x + 52°

          = 4(4°) + 52°

          = 68°
