It's C first find 3/5 of the horoziotal
18.90? I believe would be the answer . Let's see if someone else responds
2•2.5=3•-7 I'm not sure honestly that's my best guess
When the triangle is a right triangle, you can use the Pythagorean theorem. The formula would be
c^2 = a^2 + b^2
If a = 21 and c=29, thus
b^2 = c^2 - a^2
b^2 = 29^2 - 21^2
b^2 = 400
b = square root (400)
b = 20 units.
Thus, the answer is <span>D) B = 400</span>
