Answer:

5√13

Step-by-step explanation:

We know that PQWV is a square because its given. A square has all congruent sides. Therfore, VW is 10. The. length of VU is fifteen because the length of PU is 25 since PRSU is a square. We know that m<PVW is 90 degrees because PQWV is a square. Therefore, we can say the m<UVW is 90 degrees because of a straight line. Using the pythagorean therom (a^2 +b^2=c^2 (where a and b are the legs and c is the hypotenuse)) we can say that √(10^2+15^2). This equals to √325. This can be simplified to 5√13.

In Circle M, points A, B, and C are located on the circle such that measure angle CBM equals to 34 degrees. What represents angl

Bess [88]

Answer:

Angle CAB=56 degrees

Step-by-step explanation:

See the attached image for the diagram.

In triangle BMC

|BM|=|MC| (Radii of a Circle)

Therefore, triangle BMC is an Isosceles Triangle; and

$\angle CBM=\angle BCM=34^\circ$

$\angle CBM+\angle BCM+\angle BMC=180^\circ$ (sum of \angle s$ in a triangle)\\34^\circ+34^\circ+\angle BMC=180^\circ\\\angle BMC=180^\circ-68^\circ=112^\circ$

Next,

$\angle BMC=2\angle CAB $(Angle at center is twice angle at circumference)\\112^\circ=2\angle CAB\\\angle CAB=112^\circ \div 2\\\angle CAB=56^\circ$

Please help <br> thank you

Question 1:

Use the Pythagorean theorem.

If $c^2\ \textless \ a^2+b^2$ , then the angle is acute.
If $c^2=a^2+b^2$ , then the angle is right.
If $c^2\ \textgreater \ a^2+b^2$ , then the angle is obtuse.

$a=18$
$b=80$
$c=81$

$c^2=6561$
$a^2+b^2=324+6400=6724$

$\boxed {c^2\ \textless \ a^2+b^2}$

Thus, the angle is acute.

Question 2:

Take the square root of the area to get the side length.

$\sqrt{200} = \sqrt{100*2} =10 \sqrt{2}$

That's the side length. Since we have a 45-45-90 right triangle if we divide the square across its diagonal, we just multiply the side length by the square root of 2 in order to get the diagonal length.

$10 \sqrt{2} * \sqrt{2}$
$=20$

Your answer is 20 m. Hope this helps! :)

You can pick a question to answer. You don't have to do all of them. Plz plz leave a explanation of how you did it. im strugglin

mariarad [96]

Answer:

-5

Step-by-step explanation:

do the exponets first. -6 squared is positive 36 because negative times a negative is a positive.

next you multiply 4 and 7 and get 28

you have 28-36+2 and that equals -5
