Find the value of Q.

Mathematics
1 answer:
Serggg [28]2 years ago
5 0

Answer:

K = 39.5

Step-by-step explanation:

We assume that when all the angles are added together they are equal to 360°, hence:

k + 3k + 87 + 115 = 360 \\  \\ 4k + 202 = 360 \\ 4k = 360 - 202 \\  4k = 158 \\

\frac{4k}{4} =  \frac{158}{4}  \\  \\  k = 39.5
