b. Analyze Is the triangle a right triangle? How do you know?

Answers

Answer 1

Answer:

Length 1.    49

Length 2.    168

Length 3.     175

It is a right triangle

Step-by-step explanation:

7/56 x 392 = 49

24/56 = 168

7/56 = 175

It’s a right triangle because it can be noted that  *check over* 49*2 + 168*2 = 175

Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)

Answers

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)

Answer: 101 Degrees for angle BCD

Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.

The answer is in the image below.

We need to find the triangular pyramid formula which is 1/3*B*H
The base is always the bottom or foundation. To find this we need the area of the triangle at the bottom.
It is 8*6/2 or base times height divided by 2
We would get 24
This is our B value. Now height is 4 in they give us this.
Plug it in 24*4/3
We get 32 inches
