Can someone smart help me with this :)

M =  60

N = 87

Step-by-step explanation:

The exterior angle of a triangle are equal to the opposite interior angles

147 = 4y+4  + 6y+3

Combine like terms

147 = 10y+7

Subtract 7 from each side

147-7 = 10y+7-7

140 = 10y

Divide each side by 10

140/10 =10y/10

14 = y

We want to find angle M

M = 4y+4

   = 4(14)+4 = 60

And angle N

N = 6y+3

   = 6*14 +3

   =87

m<M=60

m<N=87

Step-by-step explanation:

The angle outside the triangle is always equal to the sum of the 2 angles inside the triangle that is the farthest from that angle. The angle supplementary to it doesn't count. so basically your equation to solve this problem would be

4y+4+6y+3=147  (equation)

10y+7=147 (combine like terms)

10y-7=140-7 (subtract 7 from both sides)

10y=140

10y/10=140/10 (divide by 10 from both sides)

y=14

Now you can substitute the 14 into each equation to get the measure of the angles

4y+4                                      6y+3

4(14)+4                                   6(14)+3

56+4                                      84+3

60                                          87

You can check by adding the answers together

60+87=147
