A certain building has a triangular shaped face to link up of the sides of the triangular base or 145 feet 257 feet in 290 feet five find the area of the base of the building

Answers

Answer 1

Answer:

18617.66 ft^2

Step-by-step explanation:

sides of triangular base

a=  145ft  ,

b = 257ft ,

c =  290ft

calculate the area of the base  

The base is a scalene triangle hence the area is calculated as follows

s = ( a + b + c ) / 2

  = ( 145 + 257 + 290 ) / 2 = 346

Area of triangle = [tex]\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}[/tex]

                          = 18617.66 ft^2

100

× x = 40

Multiplying both sides by 100 and dividing both sides by 170,

we have x = 40 ×

170

x = 23.53

If you are using a calculator, simply enter 40×100÷170, which will give you the answer.

HELP ASAPPPPP PLZZZZ Question in pic!!!!!

Answers

Step-by-step explanation:

Given

5y + 68 = 3y + 96 (vertically opposite angles) and

3x + 18 = 5x + 2 (vertically opposite angles)

Now solve for x.

[tex]3x + 18 = 5x + 2 \\ 3x + 18 - 5x = 2 \\ - 2x + 18 = 2 \\ - 2x = 2 - 18 \\ - 2x = - 16 \\ x = - 16 \div - 2 \\ = 8[/tex]

Now Solve for y.

[tex]5y + 68 = 3y + 96 \\ 5y + 68 - 3y = 96 \\ 2y + 68 = 96 \\ 2y = 96 - 68 \\ 2y = 28 \\ y = 14[/tex]

find the slope-intercept equation of the line that passes through (0,1) and has a slope of -2/3

Answers

Answer:

y = -2/3x + 1

Step-by-step explanation:

We already know the slope, so all we need to do is find the y-intercept. To find that, we need to plug the coordinates into the equation so far, which is,

y = -2/3x + b

1 = -2/3(0) + b

1 = 0 +b

1 = b

So the equation is y = -2/3x + 1
