Answer:

Step-by-step explanation:

We know that angles BOC and AOB are complementary angles, that is, the sum 90°. Additionally, we know that

$\angle BOC=3x+30$ and $\angle AOB = 6x-12$ , which can be expressed as

$3x+30+6x-12=90$

Let's solve for $x$

$9x=72\\x=\frac{72}{9}\\ x=8$

Using this vale, we find the measure of angle AOB

$\angle AOB = 6x-12=6(8)-12 =48-12=36\°$

Therefore, the answer is 36°.

There are two jars. One jar contains 2 red gum balls , 3 green gum balls ,and 1 yellow gumball.the other jar contains 2 blue bal

nexus9112 [7]

There are 3 green gumballs out of 6 in total. So, the odds of Jeff pulling out a green gum ball is 3/6, or 1/2.

There are 2 blue balloons out of 5 in total. So, the odds of Jeff pulling out a blue balloon is 2/5.

Therefore, the combined odds of Jeff pulling out a green gum and a blue balloon is 1/2 multiplied by 2/5, which is 2/10, or 1/5, Making the answer C.

TL;DR: The answer’s C.
