Answer:

Area = B x H + L (sum of sides of triangle)

        = 9 x 12 + 10 (12 + 15 + 9)

        = 108 + 360

        =468in^2

Either your options are wrong or question is to find lateral surface.

Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.

Lateral Surface Area = (12 + 15 + 9) x 10

                                =360in^2

Your friend says the solution to 4 x plus 24 x minus 2 equals 7 left parenthesis 4 x plus 2 right parenthesis is xequals16. Solv
kogti [31]

Answer:

Step-by-step explanation:

The given equation is

4x + 24x - 2 = 7(4x +2)

First step is to expand the parenthesis on the left hand side by multiplying each term inside the parenthesis by the term outside the parenthesis. It becomes

4x + 24x - 2 = 28x + 14

Collecting like terms such that the terms containing x will be on the lefthand side and constant terms will be on the right hand side, it becomes

28x - 28x = 14 + 2

0 = 16

0 cannot be equal to 16. Therefore, there is no solution.

The likely error of my friend was

28x - 28x = x

All the angles of a triangle add up to 180 degrees. 

30+39+<4= 180

69+<4= 180

Subtract 69 on both sides. 

<4= 111 degrees

<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.

111+<1= 180

<1= 69 degrees

I hope this helps!
