Answer:
See explanation
Step-by-step explanation:
Simplify left and right parts separately.
<u>Left part:</u>

<u>Right part:</u>

Since simplified left and right parts are the same, then the equality is true.

Answer:
Law of cosines to find missing measures
c^2= a^2+ b^2 - 2ab*cos(C)
Used because it is a SAS triangle
Step-by-step explanation:
This is known as a side, angle, side, or SAS triangle. We can find the missing measures by using the Law of cosines
c^2= a^2+b^2-2ab*cos(C)
Answer:
y = ix + 6i + 4
Step-by-step explanation:
Since the line has undefined slope or indefinite slope we connote that the slope is (i)
Slope(m) of straight line = change in y ÷ change in x
Taking another point (x,y) on the line:
i = 
i = 
Cross multiplying gives;
y - 4 = ix + 6i
y = ix + 6i + 4
