Answer:

x=25

Step-by-step explanation:

A traingle has an area of 180 degrees, so we subtract 20 and 60, and are left with 100. 5x-25=100, add 25 to get that 5x=125, divide by 5 to get that x=25.

How would I go about solving 12,15,18 thanks

grigory [225]

For 12, you would do 90=4x+42, and 48=4x, and x=12
for 15, you would do 90=8x+66, and 24=8x, and x=3
for 18, you would do 90=3x+57, and 33=3x, and x=11
