Please help, giving all my points. Geometry

Step-by-step explanation:

The shortest sides are corresponding in similar triangles

One has side length of 5, another one is 20

Scale factor is:

Since perimeter is sum of 3 sides and each side has 4 times difference, the perimeter will have 4 times the difference. So it is:

Dilation doesn't affect angle measures. A and W are corresponding angles and they measure the same.

m∡W = 5x = 5*5 = 25°

Dilation doesn't affect angle measures. B and M are corresponding angles and they measure the same.

m∡B = 2x + 30 = 2*20 + 30 = 70°

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
