Find the value of x help me pls

x=12

Step-by-step explanation:

Since the angle needs to add up to 90, you will first need to subtract 30 from 90. This will leave you with 60. Next you will divide 60 by 5 which will give you 12 which is the answer.

12

Step-by-step explanation:

30+5x=90

(90 because it is a 90° triangle)

5x=90-30( when a + change to another side it will change to -)

5x=60( solve the 90-30=60)

x=60/5(when × change to other side it will change into ÷)( and the solve it )

x=12
