Question

In a triangle LMN, ∠ = (3x +15)⁰ , ∠M = 30⁰,and ∠N = (4x ‒ 5)⁰. Find the value of x ,
∠L and ∠N

Answer 1

Answer:

X=20

Step-by-step explanation:

3x+15+4x-5+30=180

7x+40=180

7x=180-40

7x=140

X=140/7

X=20

Answer 2

Answer:

20 , 75 , 75

Step-by-step explanation:

M + N + L = 180 (ASP of triangle)

30 + 3x + 15 + 4x - 5 = 180

7x = 140

x = 20°

L = 60 + 15 = 75°

N = 80 - 5 = 75°
