What is ​ BC ​ ?<br><br><br> Enter your answer in the box.<br><br> BC=<br> units
kumpel [21]

<u>Answer:</u>

  • The length of BC is 25 units.

<u>Step-by-step explanation:</u>

<u>We know that the triangle is an isosceles triangle. Hence, we know that AB = AC. Let's first solve for x.</u>

  • => 4x + 1 = 2x + 23
  • => 4x - 2x = -1 + 23
  • => 2x = 22
  • => <u>x = 11</u>

<u>Now, let's substitute the value into the expression.</u>

  • => 3x - 8
  • => 3(11) - 8
  • => 33 - 8
  • => <u>25</u>

<u>Hence,</u><u> the length of BC is 25 units.</u>

Hoped this helped.

Please help me solve this step by step please :(
Ratling [72]

Answer:

B) 60.21 ft²

Step-by-step explanation:

Area of a triangle = 1/2bh

You can‘t used mixed measurements (feet and inches), so you have to convert each length to inches

8’6”=102’

14’2”=170’

Now find the area

1/2 x 102 x 170 = 8670 in²

This is one of the answers, but the quetion asks how many quart feet you need.

So, convert it back to feet.

8670 x 0.06944444444 = 60.2083333

(You could also have converted the two lengths to feet. 8’6” = 8.5 ft.  14’2” = 14.16666666.  This way would probably have been faster.

1/2 x 8.5 x 14.166666 = 60.20833333)
