Answer:

n = 2.8

Step-by-step explanation:

We need to solve the equation 5n+7 =21 to find the value of n.

Adding -7 on both sides

5n +7 -7 = 21 -7

5n = 14

Dividing both sides by 5

5n/5 = 14/5

n = 14/5

n = 2.8

HELPPO ME PLEASEE!!!!!!
ElenaW [278]

Answer:

Here,

x + 25° + 3x + 95° + 80°=360° (Sum of angles of a quadrilateral is 360°)

or,x+3x + 25° + 95° + 80° =360°

or,4x + 200 = 360°

or,4x = 360 - 200

or,4x = 160

or,x = 160÷4

or,x = 40

Now,

Angle K = (x + 25)° = 40 + 25° = 65°

Angle L = 3x° = 3 × 40° = 120°
