Answer:
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°
