I would mark it "not enough information". Since the question did not indicate that the two lines were parallel, we cannot assume that they are. With the given information we can solve for the value of angles 5,6,7,8, but none other.

IF the question indicated that line a was parallel to line c, we could have deduced that angle 2 was 90 degrees because "if two parallel lines are cut by a transversal, corresponding angles are congruent".

Since lines a and c are parallel and we are given that c is perpendicular to b, we can infer that b is also perpendicular to a.

So, a and b are perpendicular, the angle formed by these lines should be 90.

Hence, angle 2 is 90.

Hope this helps :)

PLEASE HELP !! ILL GIVE BRAINLIEST !!

Answer:

(a) ∠HIK and ∠GFD

Step-by-step explanation:

In this geometry, there are only two pairs of alternate exterior angles:

∠HIK and ∠GFD

∠JIK and ∠EFD

Of these, only the first pair is among the answer choices.

Alternate exterior angles are ones that are outside the parallel lines, and on opposite sides of the transversal.

six people, including A,B, and C, form a queue in a random order (all 6! orderings are equiprobable). Consider the event "B is b

mojhsa [17]

Answer:

There is a 1.39% probability that "B is between A and C in the queue".

Step-by-step explanation:

The first step to solve this problem is find the total number of possible orderings:

The first person of the queue can be any of the six. The second, can be any but the first, so five.

There are 6*5*4*3*2*1 = 720 total queue orderings.

Now we find the number of queues that B is between A and C. So:

We have:

B as the second, A as the first and C as the third

B as the second, C as the first and A as the third

B as the third, A as the second and C as the fourth

B as the third, C as the second and A as the fourth

B as the fourth, A as the third and C as the fifth.

B as the fourth, C as the third and A as the fifth.

B as the fifth, A as the fourth and C as the sixth.

B as the fifth, C as the fourth and A as the sixth.

So 8 total outcomes in which B is between A and C.

What is its probability?

$P = \frac{8}{720} = 0.0111$

There is a 1.11% probability that "B is between A and C in the queue".

Write three powers with whole number bases that have values greater than 120 and less than 130

vovangra [49]

Three powers with whole number bases that have values greater than 120 and less than 130 are:
11² = 11 x 11 = 121
5³ = 5 x 5 x 5 =125 
2⁷ = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
