(A/N If you don't know please don't answer. I need this for extra credit)

Answer:

112

Step-by-step explanation:

This is a cyclic quadralterial. A cyclic quadralterial is a quadralterial that is inscribed in a circle where all the point or vertices of the quadralterial touches the circle circumference. Opposite angles in a cyclic quadralterial are supplementary.

Angle R and Angle QPS or P is supplementary since they are opposite angle.

Substitute 68 for R

$68 + qps = 180$

$qps = 112$

So the answer is 112

Been trying to get this one answered for months, will make the first one to answer a brainliest :D Please explain how you did it

Nikitich [7]

Answer:

$\frac{2}{7}$

Step-by-step explanation:

In order to find the slope of a line you must find where the points intersect, use the formula for slope, substitute values, and simplify if needed.

In this case we were already given the points for slope:

$P1=(-4,-4) = (x1,y1)$

$P2=(-2,3)=(x2,y2)$

Slope formula:

$slope = \frac{y2-y1}{x2-x1}$

Now substitute:

$\frac{-2--4}{3--4}$

Solve using KCC: (Keep, Change, Change)

$-2+4=2$

$3+4=7$

= $\frac{2}{7}$

Because the slope isn't a negative you do not need to simplify the answer.

Hope this helps.

Which relationship in the triangle must be true?

Paul [167]

We'll assume this is an arbitrary triangle ABC.

A) No, the sines of two different angles can be whatever they want

B) sin(B)=cos(90-B)

Yes, that's always true. The "co" in cosine means "complementary" as in the complementary angle, which adds to 90. So the sine of an angle is the cosine of the complementary angle.

C) No, the correct identity is sin(180-B)=sin B. Supplementary angles share the same sine.

D) Just like A, different triangle angles often have different cosines.

Answer: Choice B
