Step-by-step explanation:

15°

Step-by-step explanation:

Hi there bud,

A right angle is 90° as you might know. So with the given information we have the angle divided into 2 parts.

1st part value : 30°

2nd part value : 4x

so we have to find the value of 4x

=== 30 + 4x = 90

moving 30 to the rhs we get

4x=60

x==60/4

x = 15°
