Since ABC is equal to DCB, you can use the angles given in triangle ABC in triangle DCB. Since the sum of the angles in a triangle is 180, the equation would be this:
90+46+x=180 

Solve for x in that and you're good :)

Use trig so the side with 4x-7 is also equal to 21sin(46)=15 so 4x-7=15.1. thus x=5.52 which is around 6

What is the area of the trapezoid with height 10 units?
aleksley [76]

If by "long leg lengths" you mean the hypotenuse then the area is 116 sq. units.  If you mean the bases of the triangles then the area is 170 sq. units.

If the length of 12 is the hypotenuse, we first must find the base of the triangles using the Pythagorean theorem:

10² + b² = 12²

100 + b² = 144

b² = 44

b = √44 = 6.6

This means we have two triangles and a rectangle.  The area of the rectangle is 5(10) = 50 sq. units.  The area of each triangle is 1/2(6.6)(10) = 33.  Adding all 3 together we have:

50+33+33 = 116 sq. units.

If the 12 is the base, then we have the rectangle with the area of 5(10) = 50 and two triangles each with an area of 1/2(12)(10) = 60:

50+60+60 = 170 sq. units.

qwelly [4]
A line with an undefined slope would be vertical, meaning the x-coordinate will not change regardless of where the y-coordinate is.

Therefore, the equation would simply be x= -2

This is b/c x does not ever change (it is a vertical line)
while y could be any number on that line
