The measure of angle B is equal to 60 degrees.

In order to find this, we can first note that the angle C (in the right side triangle) is equal to 80 degrees. We can tell this because it creates a straight line with the other angle C and therefore the two combined give us 180 degrees.

Then we can add angle A, B and C together in the right side triangle to get 180 degrees since they are all the measures of angles in a triangle.

A + B + C = 180

2x + 3x + 80 = 180

5x + 80 = 180

5x = 100

x = 20

Now that we have the x value, we can plug into the equation for B.

B = 3x

B = 3(20)

B = 60

Ill Mark Brainliest if you answer correctly. The figure below shows a shaded circular region inside a larger circle:

pogonyaev

First we have to find the areas of both circle using the formula

$Area = \pi r^2$

For larger circle,

$Area= \pi(5)^2 = 25 \pi$

For smaller circle,

$Area = \pi (4)^2 = 16 \pi$

Required probability

$= \frac{25 \pi -16 \pi}{25 \pi} *100 = \frac{9}{25}*100 = 36%$

Correct option is the second option .

How do you find the legs of a right triangle when only given the hypotenuse?

tangare [24]

Answer:

We know that a^2+b^2=c^2. The 45° angle lets us know that y=x (45+45+90=180), so the problem is y^2+x^2=4sqrt of 2

$4 \sqrt{2} = \sqrt{32 } \\ \sqrt{32} ^{2} = 32$

So you get y^2+x^2=32, and from there, since we know x and y are equal, you can just divide 32 by 2 then take the square root of that, so the answer should be 4 for both x and y
