Answer:

99

Step-by-step explanation:

8 + 7(4^2 - 3)

Solve what’s in the parentheses first, starting with 4^2:

8 + 7(16 - 3)

Continue solving what’s in the parentheses:

8 + 7(13)

Considering the order of operations, multiply 7(13) before adding 8:

8 + 91 = 99

⦟KLJ and ⦟JLM are a linear pair. Find the measures of ⦟KLJ and ⦟JLM.
KATRIN_1 [288]

Answer:

Step-by-step explanation:

6x + 12 + 4x + 8 =  180 {Linear pair}

6x + 4x + 12 + 8 = 180 {Combine like terms}

         10x + 20  = 180   {Subtract 20 from both sides}

              10x =  180 - 20

             10x  = 160    {Divide both sides by 10}

               x = 160/10

                x = 16

m∠KLJ = 6*16 + 12

            = 96 +12

            = 108

m∠JLM = 4*16 + 8

            = 64 + 8

            = 72
