Two angles of a quadrilateral measure 305° and 30°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?

10 and 15

Step-by-step explanation:

A quadrilateral will measure a total of 360 degrees. We already know that the measurements of other angles were 305 and 30. That's a total of 335 degrees. Subtract that from 360 to find out how many are left in the shape.

360 - 335 = 25. The other two angles are in a ratio 2:3. So you need to find numbers that add up to 25 in a ratio of 2:3

If you multiply that ratio by 5, you get 10:15. 10 and 15 add up to 25, so those are your other angles.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
