Answer:153.86
Step-by-step explanation:
Answer:
42%
Step-by-step explanation:
To find the percent of decrease first find the difference between 32.25 and 18.70.
32.25 - 18.70 = 13.55
Now divide this number by the original number, in this case 32.25, and then multiply the answer you get by 100.
13.55 / 32.25 = 0.42
Multiply this number by 100 to get the percentage.
0.42 * 100 = 42
Angles ∠MOK and ∠NOL are identical by opposite angle theorem.
∠M = ∠N through given information
∠MKO and ∠NLO are congruent. Since the other two angles of each triangle are equivalent, the last angle must be equivalent to the last angle of the other triangle. (180 - ∠1 -∠2 = ∠3); you could also prove ∠MKO = ∠NLO by stating that the opposite sides of the two angles are congruent.
ΔMKO and ΔNLO by Angle-Angle-Side theorem
since ΔMKO and ΔNLO, all corresponding parts of both triangles are congruent, so therefore MO ≅ NO

ANSWER

EXPLANATION
We want to find the exact value of cos(150°).
150° makes an angle of 30° with the positive direction of the x-axis and it is also in the second quadrant.
The cosine ratio is negative in the second quadrant.
Using the unit circle,
