BRAINLIEST + 5 STAR! :D
Solve for × on the diagram below :D

Answer 1

Answer:

x=12

Step-by-step explanation:

90-42= 48

48/4=12

X=12

42+12=54

3(12)= 36

54+36=90

Answer 2

Answer:

x=12

Step-by-step explanation:

Since it is on a right angle we can equate both angles to 90:

3x+x+42=90

Now we simplify:

4x+42=90

Subtract 42 from both sides:

4x+42-42=90-42

Simplify:

4x=48

Divide both sides by 4:

4x÷4=48÷4

Simplify:

x=12
