Question

Use the given information to draw a right triangle. Use trigonometric ratios and a calculator to find the unknown sides and angles. Round off sides and angles to the same number of decimal places as the given sides and angles.

*a* = 6.0 and *b* = 9.0

Answer #1

Use vectors to find the interior angles of the triangle given
the following sets of vertices. Round your answer, in degrees, to
two decimal places.
(−7,−4)(−7,−4), (−5,7)(−5,7), (3,2)

Let the angles of a triangle be α, β, and
γ, with opposite sides of length a, b,
and c, respectively. Use the Law of Cosines to find the
remaining side and one of the other angles. (Round your answers to
one decimal place.)
α = 46°; b =
12; c = 18

Find the slope of each side of the triangle and use the slopes
to find the measures of the interior angles. (Round angle measures
to one decimal place.)
A (-4,6) B- (3,4) C- (1,2)
Find the Slope of AB, AC, BC and Degree of A,B,C

20. A piece of land is shaped like a right triangle. Two people
start at the right angle of the triangle at the same
time, and walk at the same speed along different legs of the
triangle. If the area formed by the positions of the
two people and their starting point (the right angle) is changing
at 5 m2/s, then how fast are the people moving
when they are 2 m from the right angle? (Round your answer to...

Use the given information to find the tabled value for an
F variable based on n1 − 1 numerator degrees of
freedom, n2 − 1 denominator degrees of freedom with an
area of a to its right. (Round your answer to two decimal
places.)
n1 = 13, n2 = 19, a = 0.100

Use the given degree of confidence and sample data to find a
confidence interval for the population standard deviation σ. Assume
that the population has a normal distribution. Round the confidence
interval limits to the same number of decimal places as the sample
standard deviation.
Weights of men: 90% confidence; n = 14, xbar = 156.9 lbs, s =

8.7lbs < σ < 14.3lbs...

A graphing calculator is recommended.
A grassroots group opposed to a proposed increase in the gas tax
claimed that the increase would hurt working-class people the most,
since they commute the farthest to work. Suppose that the group
randomly surveyed 24 individuals and asked them their daily one-way
commuting mileage. The results are below. Using a 5% significance
level, test the hypothesis that the three mean commuting mileages
are the same. (Let 1 = Working-class, 2 = Professional (middle
incomes),...

A variable is normally distributed with mean 18 and standard
deviation 4. Use your graphing calculator to find each of the

b) Find the area to the left of 13.
c) Find the area to the right of 15.
d) Find the area to the right of 21.
e) Find the area between 13 and 29.
