Find the area of the isoscelus, full working out x

60

Step-by-step explanation:

Use the Pythagorean Theorem to find the height. 13 squared minus 5 squared=144

Square rt= 12

Now use the formula (base times height) divided by 2  

(10 x 12)/2

120/2

60

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
