One of the same side angles of two parallel lines is five times smaller than the other one. Find the measures of these two angle

shutvik [7]

Answer:

30 and 150

Step-by-step explanation:

Whether these are same side interior or same side exterior, the sum of them is 180 when the angles are on the same side of a transversal that cuts a pair of parallel lines. Let's call the angles A and B. If angle A is 5 times smaller than angle B, then angle B is 5 times larger than angle A. So the angles are x and 5x. They are supplementary so

x + 5x = 180 and

6x = 180 so

x = 30 and 5(30) = 150

*15 Points* Factor Using Difference Of Squares (With Steps/Work) 16a^2 - 36

larisa [96]

4 • (2a + 3) • (2a - 3)

(1): "a2" was replaced by "a^2".

24a2 - 36

3.1 Pull out like factors :

16a2 - 36 = 4 • (4a2 - 9)

3.2 Factoring: 4a2 - 9

Look at the picture below. What is tan(A – B)? Thanks!

Natalka [10]

Step-by-step explanation:

the mistake was made when the value of cos 3 pi over 2 was calculated.

tan(A-B)= ?since tan=sin/cos

sin(A-B) = sinAcosB-cosAsinB

cos(A-B) cosAcosB+sinAsinB

divide by cos on the RHS

tan(A-B)= tanA-tanB

1+tanAtanB
