Outcome 1: Use trigonometric ratios to solve problems involving right triangles.
Target
Can you do this?
1.1 I can determine values of the
sine, cosine, and tangent
function of an angle in standard
position.
Suppose the terminal side of an
angle in standard position with
measure Θ contains the
indicated point. Find sin Θ, cos
Θ, and tan Θ.

b. P(3,6)
a) Determine the sin A, cos A,
tan A for the right triangle ABC
where C is a right triangle,
BC  10 ft , and BA  15 ft. In
triangle ABC, find the measure
of angle A to the nearest
degree.
b) The angle of elevation to the
top of the Empire State Building
in New York is found to be 11
from the ground. Using this
information, find the height of
the Empire State Building.
a) Given triangle ABC, measure
of angle A is 53, measure of
angle B is 79, and AB= 25, find
the length of AC.
b). Triangle JKM, the measure of
angle K is 63, JK = 27, and KM =
13.
c) Given triangle XYZ, measure
of angle Z is 87, ZY = 15, XZ = 37,
Find the length of XY, and angle
X.
1.2 I can solve problems
involving indirect measures of
sides and angles that can be
modeled as parts of right
triangles.
1.3 I can apply the law of sine
and cosine to any triangle.
