Answer:
-2/-5 = 2/5
Step-by-step explanation:
Answer:
x=-5
Step-by-step explanation:
Vertical lines have the same x value all the time. They are of the form x=
Since it passes through the point (-5,-2) the x value must be -5
x=-5
Applying the law of cosines, the measure of angle Y in the image below, to the nearest whole degree, is: B. 64°
<h3>What is the Law of Cosine:</h3>
Law of cosines is given as: y² = x² + z² – 2xz(cosY)
Given the following:
x = 12
y = 16
z = 17
Y = ?
Apply the law of cosines:
16² = 12² + 17² – 2(12)(17)(cosY)
256 = 433 - 408(cos Y)
256 - 433 = -408(cos Y)
-177 = -408(cos Y)
-177/-408 = cos Y
Y = cos^(-1)(177/408)
Y ≈ 64°
