3(2)+2(3)=12 <<<< is the answer! :)
Solve like a regular equation
A=1/2 b x h
multiply by 2 to eliminate the fraction
2A =b x h
divide by h
2A/h= b
hope this helps

Answer:
<em>x=8</em>
Step-by-step explanation:
<u>Triangles</u>
An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.
The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:
8x+3=67
Reducing:
8x=67-3=64
Solving:
x=64/8
x=8
