Answer:

$x=30^{\circ}$

Step-by-step explanation:

Looking at $\triangle LMN$ :

$\angle NML = 180 - (90+45)$ (angle sum of triangle is $180^{\circ}$ )

$=45^{\circ}$

Looking at $\triangle KNM$ :

$\angle KNM = 180-105$ (angle of straight is $180^{\circ}$ )

$=75^{\circ}$

$\angle KNM + \angle NKM + \angle KMN = 180$ (angle sum of triangle is $180^{\circ$ )

$75+2x+45 = 180$

$2x+120 = 180$

$2x=60$

$x=30^{\circ}$

Hope this helps :)

A & B share the cost in a ratio of 3:2. A pays £125, how much does B pay?

guajiro [1.7K]

Let the common multiple be x
3x : 2x
3x = 125
x = 125/3

So, B pays 2x = 2 × 125/3 = £250/3

Sam is selling T-shirts to raise money for School research project.

iren [92.7K]

Answer:

Step-by-step explanation:

Equation y = 3x + 210

if y = 10x

10x = 3x + 210

or, 10x - 3x = 3x + 210 - 3x

or, 7x = 210

or, x = 210 ÷ 7

or, x = 30
