If angle YWZ = 17, what is angle WXY?
marusya05 [52]
We know that

step 1
if ∡YWZ=17°
then
∡XWZ=17°*2-----> 34°----> because triangle XWY and triangle YWZ are congruents

step 2
∡WXY=∡WZY-------> because triangle XWY and triangle YWZ are congruents
we know that 
<span>the sum of the internal angles of a triangle is 180 degrees
</span>so
180°=∡XWZ+2*∡WXY---------> ∡WXY=[180-∡XWZ]/2
∡WXY=[180-34°]/2-------> ∡WXY=73°

the answer is
∡WXY=73°

Solve the following equation, and explain your solution method.x³+7x²-x-7=0
Korvikt [17]

Answer:

x_{1}=-1\\ x_{2}=1\\ x_{3}=-7

Step-by-step explanation:

The easiest way to solve this equation is to first find and highlight a common factor between two terms. In this case, x^2 can be factored to rewrite the equation as follows:

x^{2} (x+7)-x-7=0\\x^{2} (x+7) = (x+7)

The (x+7) term can be crossed out on both sides and then for this equation to be true, there are two possibilities:

Either

x^{2} =1\\x_{1} = 1\\x_{2} = -1

or

(x+7) = 0\\x_{3} = -7

Therefore, the solutions to this equation are -1, 1 or -7.
