Answer:
Step-by-step explanation:
Trapezoid ABCD is isosceles trapezoid, because AB = CD (given). In isosceles trapezoid, angles adjacent to the bases are congruent, then
Since BK ⊥ AD, the triangle ABK is right triangle. In this triangle, AB = 8, AK = 4. Note that the hypotenuse AB is twice the leg AK:
If in the right triangle the hypotenuse is twice the leg, then the angle opposite to this leg is 30°, so,
Since BK ⊥ AD, then BK ⊥ BC and
Thus,
Now,
<span>17x-2=7x+8
We simplify the equation to the form, which is simple to understand
<span>17x-2=7x+8
We move all terms containing x to the left and all other terms to the right.
<span>+17x-7x=+8+2
We simplify left and right side of the equation.
<span>+10x=+10
We divide both sides of the equation by 10 to get x.
<span>x=1</span></span></span></span></span>
Answer:
W=2
Step-by-step explanation:
First you have to fill A in as 19 because thats how many culinary recipes that she will need to know
Second you then have to get the variable W by itself so you would subtract 17 from the side that W is on
Once you subtract 17 from one side you have to subtract from the other
So therefore W would =2
