Answer

54 degrees

Step-by-step explanation:

Using angle sum property(angles in a triangle add up to 180),

y+y+72=180

2y+72=180

2y=180-72

2y=108

y=108/2

y=54 degrees

pls mark brainliest

hope it helped

Answer:

A 54

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

72+y+y = 180

Combine like terms

72 +2y = 180

Subtract 72 from each side

72-72 +2y = 180-72

2y = 108

Divide by 2 on each side

2y/2 = 108/2

y = 54

I need help with both of these problems

GREYUIT [131]

The first question is D because if the
y-intercept is 1 then every point moves down three units.

The second question is J because a vertical line is not a function so it can’t be a linear function.

liberstina [14]

Answer:

x > -2

Step-by-step explanation:

Solve the inequality -4x < 8 using inverse operations. If you divide or multiply by a negative, flip the inequality sign.

$-4x < 8\\\\\frac{-4x}{-4} < \frac{8}{-4}$

x > -2

Which statements are true about a rectangular pyramid with a height of 9 centimeters and a base with the dimensions of 4 centime

Semmy [17]

Answer:

B. The area of the base of the pyramid, B, is 24 centimeters squared.

C. A rectangular prism with the dimensions of 9 centimeters by 4 centimeters by 6 centimeters will have 3 times volume of this pyramid.

Step-by-step explanation:

Given a rectangular pyramid with:

Height=9 cm

Base Dimensions = 4 centimeters by 6 centimeters

Base Area B=4 X 6 =24 Square cm.

Therefore, Option B (The area of the base of the pyramid, B, is 24 centimeters squared) is correct.

Volume of a pyramid = $\frac{1}{3} $ X Base Area X Height$

$=\frac{1}{3} X 24X9=72 cm^3$

Volume of a Prism with the dimensions of 9 centimeters by 4 centimeters by 6 centimeters

=Base Area X Height

=24 X 9

$=216 cm^3$

Now, 216/72=3

Therefore, A rectangular prism with the same dimensions will have 3 times volume of this pyramid

Therefore, <u>Option C is correct.</u>
