Answer:
x=15
m<ABC=30
m<BCA=60
m<CAB=90
Step-by-step explanation:
to find the value of x I used the 5x+15 since we know that is a right angle. so we equal 5x+15 to 90. you subtract 15 to both sides and then get 5x=75 and then divide by 5 to both sides to get x=15. you the plug in the 15 to the other parts, so 2x=2(15)=30 and 4x=4(15)=60
