Question

If x,2x,3x and 4x form a complete angle, find the greatest angle​

Answer 1

since x 2x 3x and 4 x form a complete angle

x+2x+3x+4x = 360

10x = 360

x= 36

greatest angle is 4×36 = 144°

Answer 2

Answer:

144°

Step-by-step explanation:

Complete angle = 360°

According to question,

$x + 2x + 3x + 4x = 360 \\ \\ 10x = 360 \\ \\ x = 36$

Therefore, The greatest angle is 4x

= 36 × 4

= 144°

Note:

Angle : A shape, formed by the intersection of two straight lines or rays from a common point which is known vertex.
