Setler79 [48]
Let's say x is longest side, y is shortest side and z is the other side. So we have some equations such that

x+y+z=57 (by the first sentence)

x=(y+z) -3 (by the second sentence)

2y=x-15  (by the third sentence)

By the second equation, we have y+z=x+3 and if we use it in the first equation, then x+y+z=x+(x+3)=57. So x=27

Since x=27, if we use it in the third equation the we have 2y=x-15=27-15=12 then y=6

Therefore z=24

Help I’m almost out of time
VladimirAG [237]

Answer: First option.

Step-by-step explanation:

You can idenfity in the figure that \angle FCE is formed by two secants that intersect outside of the given circle.

It is important to remember that, by definition:

 Angle\ formed\ by\ two\ Secants=\frac{1}{2}( Difference\ of\ intercepted\ Arcs)

Knowing this, you can set up the following equation:

m\angle FCE=\frac{1}{2}(BD-FE)

Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle \angle FCE.

This is:

m\angle FCE=\frac{1}{2}(112\°-38\°)\\\\m\angle FCE=37\°
