Answer:

8 in, 8 in and 20 in

Step-by-step explanation:

Let the equal sides of the isosceles triangle be x, then

The base = 2.5x

Sum the 3 sides and equate to the perimeter of 36

x + x + 2.5x = 36

4.5x = 36 ( divide both sides by 4.5 )

x = 8

Thus the 2 equal legs = 8 in

base = 2.5x = 2.5 × 8 = 20 in

Answer:

1.187991

Step-by-step explanation:

sin^2(225)−(cos(330))(cos(240))

=(−0.930095)2−(cos(330))(cos(240))

=0.865076−(cos(330))(cos(240))

=0.865076−−0.991199(cos(240))

=0.865076−(−0.991199)(0.325781)

=0.865076−(−0.322914)

=1.187991

You just have to figure it where you can place 2 solid lines and get 10 triangles ( i can only get 9). Think about the pentagon in the middle of the triangles and see if somehow you can create more triangles using only the two straight lines.
