Answer:
angle 9 measures 105 degrees
Step-by-step explanation:
measure of angle 8 is congruent to measure of angle 11 (alternate-interior angles are congruent)
measure of angle 11 is congruent to measure of angle 9 (corresponding angles are congruent)
therefore, measure of angle 8 = measure of angle 9
I got you- The answer is (B. 4) hope this helps, if you need me to explain ask in the comments. Have a good day/night:)
The correct Option is (C) 5x(3x^2 + 4)
Explanation:
15x^3 + 20x
Take common terms out:
5x(3x^2 + 4) Which is option C.
X=5.4 and Y=10.5.
Used the law of cosine equation, then SOHCAHTOA, and then Pythagorean theorem.
