Question

can you please solve these questions ​

Answer 1

Answer:

1. 170°

2. 36°, 72°, 108°, 144°

Answer 2

Answer:

1. solution

so , let's consider 4th angle be x

As we know angles of quadrilateral is 360 degree.

100 + 60 + 30 + x = 360

190 + x = 360

x = 360 - 190

x = 170 degree

therefore 4th angle is 170 degree

2. solution

let's consider angles be

x , 2x , 3x , 4x

so ,

x + 2× + 3x + 4x = 360

10x = 360

x = 360 ÷ 10

x = 36

first angle x = 36 degree

second angle 2x = 2 × 36 = 72 degree

third angle 3x = 3 × 36 = 108 degree

fourth angle 4x = 4 × 36 = 144 degree
