Answer:

x = 5

Step-by-step explanation:

The base angles ,A and C are equal

A = C = 73

The sum of the angles of the triangle are 180

A+C+B =180

73+73 + 6x+4=180

6x+150=180

Subtract 150 from each side

6x+150-150=180-150

6x = 30

Divide by 6

6x/6 = 30/6

x = 5

weeeeeb [17]

Long Piece: x + 18

Short Piece: x

(x) + (x + 18) = 84

2x + 18 = 84

2x = 66

x = 33

Long Piece: x + 18 = (33) + 18 = 51

Answer: 33 meters and 51 meters

Ho do you get the Surface Area of this shape?

blsea [12.9K]

This solid object contains 8 sides.

The side that is facing you has a surface area:

$64f{ t }^{ 2 }+84f{ t }^{ 2 }=148f{ t }^{ 2 }$

The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.

The bottom side has a surface area:

$84f{ t }^{ 2 }$

The side to your right has a surface area:

$84f{ t }^{ 2 }$

The side to your left has a surface area:

$48f{ t }^{ 2 }$

The side to your top left has a surface area:

$48f{ t }^{ 2 }$

The side beside the side to the top left has a surface area:

$36f{ t }^{ 2 }$

The side at the very top has a surface area:

$36f{ t }^{ 2 }$

Combined, the surface area is:

$S=2\cdot 148f{ t }^{ 2 }+2\cdot 84f{ t }^{ 2 }+2\cdot 48f{ t }^{ 2 }+2\cdot 36f{ t }^{ 2 }$

$\\ \\ =296f{ t }^{ 2 }+168f{ t }^{ 2 }+96f{ t }^{ 2 }+72f{ t }^{ 2 }\\ \\ =632f{ t }^{ 2 }$

Therefore the answer is: C

What is the slope and y-intercept for the line represented by this equation?

alexira [117]

5x + 13y = -13
13y = -5x - 13
y = -5/13x - 13/13
y = -5/13x - 1

Slope = -5/13
y-intercept = -1
