Question

Plis tolong di jawab kk!

Answer 1

Verified answer

< K+ < L+ < M = 180

x + (5x-7) + (2x-13) = 180

8x - 20 = 180

8x = 200
x = 25

< LKM = < K
< K = X

< LKM = 25


< KLM = < L
< L = 2x-13

< KLM = 2(25) - 13
= 50 - 13
= 37

Answer 2

Jawab

<K + <L + <M = 180°
x + 2x - 13° + 5x - 7° = 180°
x + 2x + 5x - 13° - 7° = 180°
8x - 20° = 180°
8x = 180° + 20°
8x = 200°
x = 200°/8
x = 25°

maka,
a) <LKM atau <K
= x
= 25°

b) <KLM atau <L
= 2x - 13°
= 2(25°) - 13°
= 50° - 13°
= 37°

semoga membantu
