Victor drew trapezoid PQRS on a coordinate plane p(7,4) q(10,4) r(13,-1) s(8,-1) what is length in units of side ps

olga nikolaevna [1]

Answer:

PS= $\sqrt{26}units$

Step-by-step explanation:

Given : PQRS is a trapezoid on a coordinate plane P(7,4) Q(10,4) R(13,-1) S(8,-1).

To find:: Length of the side PS

Solution : Using the distance formula, we can find the length of the side PS, therefore

PS= $\sqrt{(y_{2}-y_{1})^2+(x_{2}-x_{1})^2}$

PS= $\sqrt{(-1-4)^{2}+(8-7)^2 }$

PS= $\sqrt{(-5)^2+(1)^2}$

PS= $\sqrt{25+1}$

PS= $\sqrt{26}units$

which is the required length of the side PS.

The odds against Carl beating his friend in a round of golf are 9:7. Find the probability that Carl will lose?

grandymaker [24]

The ratio 9:7 gives you following statement:

Carl will win in 9 cases from 9+7=16;
Carl will lose in 7 cases from 16.

Then the probability that Carl will lose is

$Pr(\text{Carl will lose})=\dfrac{7}{16}.$

Answer: $Pr(\text{Carl will lose})=\dfrac{7}{16}.$

The sum of 2 of the exterior angles of a triangle is 222 degrees. What is the measure of the third exterior angle?

zysi [14]

Answer:

Exterior angles always add up to 360 degrees, therfore 360 - 222 = 138

Step-by-step explanation:

360 - 222 = 138

the answer to your question is 138degrees.

For any shape the exterior angles will always add up to 260 degrees.

Hope this helps in the future!
