Angle K = angle M

(4x-1)=(2x+27)

4x-2x=27+1

2x=28

x=14

K=4x-1 then 4(14)-1
55 degrees
M=2x+27 then 2(14) +27
55 degrees
K+M+L =180
55+55+L=180
110+L=180
L=70 degrees
Therefore K=55 degrees M=55 degrees L=70 degrees

Subract (21x) - (-16 + 7x) can someone help me
koban [17]

The solution to (21x) - (-16 + 7x) is 14x + 16

<h3><u>Solution:</u></h3>

Given that (21x) - (-16 + 7x)

We have to evaluate the given expression

Let's look at the given expression

(21x) - (-16 + 7x)

Multiply the terms within second bracket with minus sign

<em><u>There are two simple rules to remember:</u></em>

  • When you multiply a negative number by a positive number then the product is always negative.
  • When you multiply two negative numbers or two positive numbers then the product is always positive

⇒ (21x) + 16 - 7x

Removing the parenthesis

⇒ 21x + 16 - 7x

Combining the like terms,

⇒ 14x + 16

Thus the solution is 14x + 16
