As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.

A=\frac{1}{2}bh

Where b represents base (hypotenuse) and h as height of the triangle.

We know that:

b=13cm \\h=4cm

Using this data we fill the formula.

A=\frac{1}{2}\cdot13\cdot4=\frac{13\cdot4}{2}=13\cdot2=\boxed{26cm^2}

Hope this helps.

PLEASE HELP!!!!! explain too please
ale4655 [162]

Answer:

8. Not similar

9. Similar

Step-by-step explanation:

8. You could try to us the AA theorem which means that two angles in the triangle are equal, which would mean that the triangles are similar. But 46+58=104 and 180-104=76 so there are not two similar angled between the triangles.

9. You can use the same theorem for this problem (AA). So 106+31=137 and then 180-137=43 which is one of the angles in the second triangle. Since at least two of the angles are equal, you can use AA theorem yo prove they are similar.

Hope this helps!
