Question

What is the value of k​

Answer 1

a

Explanation:

yes

Answer 2

k=10°

Explanation:

<ZYX

<ZYM + <ZYX = 180° ( angle on straight line)

115° + <ZYX = 180°

<ZYX = 180° - 115°

<ZYX = 65°

k

<YZX + <ZXY + <ZYX = 180° ( sum of interior angles of a triangle)

(4k + 5)° + (6k + 10)° + 65° = 180°

10k + 80° = 180°

10k = 180° - 80°

10k = 100°

Multiplying both sides by 10

k = 100°

10

k = 10°
