Hi there!

If KLM is an isosceles triangle, then KM = LM.

4d - 13 = 12 - d

Solve for d. Add 'd' to both sides:

5d - 13 = 12

Add 13 to both sides:

5d = 25

Divide both sides by 5:

<u>d = 5 units.</u>

What are the results of these tasks? =<br> 4x-3=5x-3<br><br> -2x=3x-5
frez [133]

Step-by-step explanation:

I think you are trying to find x, I dunno, but if you are here's the solution.

when trying to find x, your main goal is to shift all x terms to one side.

For the first one

4x-3 = 5x-3

Carry all x terms to one side:

(4x-3)-5x = (5x-3)-5x

4x-5x-3 = -3

Shift all constants (purely just numbers, no x) to the other side

(4x-5x-3)+3 = (-3)+3

4x-5x = 0

-x = 0

x = 0

The second one:

-2x = 3x-5

5x = -5

x = -1

Done, have fun with math!

What is the measure of angle B in the triangle?
sladkih [1.3K]
40 + 2x - 30 + x + 20 = 180
3x + 30 = 180
3x = 150
  x = 50

m<B = 2x - 30
m<B = 2(50) - 30
m<B = 100 - 30
m<B = 70
