Question

Plz solve this problem!

Answer 1

Step-by-step explanation:

sum of all angle = 360

k + 150 + k - 15 + 30 + 90= 360

2k+255=360

2k= 360-255

2k= 105

k= 105/2

= 52.5

Answer 2

Sum of the angles=360

Therefore; (k - 15) + 30 + 90 + (k + 150)=360

-15 + 30 + 90 + 150 + k + k= 360

255 + 2k= 360

2k= 360 - 255

k= 105÷2

k= 52.5
