2x=22+73-11-23-67
2x=-6
divide both sides by 2
x=-3
Answer:
m∠A = 45.86°
Step-by-step explanation:
A rough sketch of the triangle is shown in the attached pic.
When 3 sides are given and we want to solve for an angle, we use the Cosine Rule. Which is:
Where a, b, p are the lengths of 3 sides (with p being the side opposite of the angle we are solving for) and P is the angel we want to solve for
Thus, we have:
Answer: A = X + Y; B = X xor Y. The task is to make X as minimum as possible.
Step-by-step explanation:
He should use the mean because there are no outliers that affect the mean.
