Answer:
x = 22.2
Step-by-step explanation:
Let's set up this problem using cosine law:
x^2 = a^2 + b^2 -2abcos110
where a = 12, b = 15
x^2 = (12)^2 + (15)^2 - 2(12)(15)cos110
= 144 + 225 - 360(-0.342)
= 492
x = 22.2
Answer:
a=79, b=101
Step-by-step explanation:
the consecutive angles are supplementary angles, and the opposite ones are congruent.
The correct answer is A. +3, unless inside parentheses, indicates a positive vertical change, thus the function would move upward. If the function looked like 2(x^3 + 3) the change from the +3 would be horizontal (left) instead.
