J=(7x+13) K=(83-2x) and the sum of the measures of the angles is 141. What is the measure of each angle
natta225 [31]

Answer:

j=76 and k=65

Step-by-step explanation:

j + k = 141 \\ 7x + 13 + 83 +  - 2x = 141 \\ 96 + 5x = 141 \\ 5x = 141 - 96 \\ 5x = 45 \\ x =  \frac{45}{5}  \\ x = 9 \\ j = (7 \times 9 + 13) \\ j =76 \\ k = 83 - 2(9) \\  = 83 - 18 \\  = 65
