Help! ASAP ONLY IF YOU KNOW ty!

Answer: 115 degrees

Step-by-step explanation:

Since a kite has one pair of opposite angles which are congruent, W and Y must be congruent because X and Z are not.

The sum of the angles in any quadrilateral is 360 degrees. We know two of the angles as 90 degrees and 40 degrees, so the sum of the other two angles must be 360-90-40 = 230 degrees.

We know that W and Y must be equal so each of them is equal to 230/2 degrees = 115 degrees.

Answer:

The slope is again 1

Step-by-step explanation:

Because x1 and x2 is 5 and 8, and y1 and y2 are 5 and 8, the slope equation becomes 5-8 / 5-8, which would turn into -3 /-3, or 1.

Is it ever possible that cos (A−B)=cos ⁡A−cos ⁡B? Why or why not?

Nookie1986 [14]

Answer:

The given equation is never possible i.e cos ( A - B ) ≠ cos A - cos B

Step-by-step explanation:

Given as :

Is cos ( A - B ) = cos A - cos B

To check this possibility , Let us put the value of angle A and B on both side of equation

Now, Let A = 60° and B = 30°

From Left hand side equation

cos ( A - B ) = cos ( 60° - 30° )

Or, cos ( A - B ) = cos 30°

∴ cos ( A - B ) = $\frac{\sqrt{3} }{2}$

or, cos ( A - B ) = 0.866

From Right hand side equation

cos A - cos B = cos 60° - cos 30°

Or, cos A - cos B = $\frac{1}{2}$ - $\frac{\sqrt{3} }{2}$

∴, cos A - cos B = 0.5 - 0.866

I.e cos A - cos B = - 0.366

So, Left hand side ≠ Right hand side

Since while equating the values of angle A and b in the given equation on both sides, we get that the value of both sides are not equal , Thus we can say that the given equation is not equal to each other .

Hence given equation is never possible i.e cos ( A - B ) ≠ cos A - cos B Answer
