X+30+70=180
x+100=180. -100 both sides
x=80
|x=80° |
The answer to this problem is 7
If i were you, i would add one to 7x and fifteen. this gives you x^2+8x+16, a perfect square of x+4.
Prisms are polyhedra with two parallel, congruent (faces) called bases.
<span>The answer is one. First, these are both straight lines, meaning they will have one intersection point. In order to find the intersections of these two lines, we must set them equal to one another. So x + 5y = 6 equals 3x + 30y = 36. When you solve the two equations together, you'll get one intersection point at (0 , 1.2).</span>
