How do I find the value of x here?

Vertical angles are equal, so the angle above 2 is also 88+x. Then, because the 2 sides of the 52° triangle are congruent, the angles beneath them are too. So you are left with the equation of that triangle being...

88 + x + 88 + x + 52 = 180
combine like terms
228 + 2x = 180
subtract 228 from both sides
2x = -48
divide both sides by 2
x = -24

Hope this helps :)

Suppose Gabe, an elementary school student, has just finished dinner with his mother, Judy. Eyeing the nearby cookie jar, Gabe a

Paladinen [302]

Answer:

0.56

Step-by-step explanation:

What is the probability that his mother returns just in time to catch Gabe stealing a cookie?

The probability of this is the same as 1 minus the probability that Gabe is NOT caught.

- Judy could return at anytime in the next 90 seconds

- Gabe spends the first 40 seconds pondering... time wasted=40secs

- It takes 30 seconds (out of the remaining 50secs) to finish eating a cookie without a trace

- The question says that Gabe was going to do it, so he probably did

Now we're looking for the probability that he gets caught. That is, probability that he does not "successfully" complete the 30secs task within the remaining 50secs.

Remember that each second has an equal probability of being the second that Judy comes back in. The latter of the 90 seconds does not carry a higher probability!

So the probability of catching Gabe (despite the 30secs it takes to complete his task) is 50/90 which is equal to 0.56
