Two parallel lines, e and f, are crossed by two transversals. what is the measure of < 15? m< 15 = 77° m< 15 = 83° m< 15 = 93° m< 15 = 97°

The correct option is 4.

Step-by-step explanation:

Given information: and .

If a transversal line intersects two parallel lines, then alternate exterior angles  are same.

In the given figure line e and f are parallel to each other. The transversal line d intersects the parallel lines.

Since angle 10 and angle 15 are alternate exterior angles, therefore

Therefore measure of angle 15 is 97 degrees and option 4 is correct.

D

Explanation:

pro

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

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

see the picture for the graph.
