Using this triangle, what theorem can you use to find the missing side with the correct set up?
Tangent = Opposite/Adjacent 14/21 =
Pythagorean Theorem 142 + 212 = c2
Pythagorean Theorem 142 + b2 = 212
What is one tool to use to find x?
tan-1 80/40 (Inverse Tangent)
x = 80 (Isosceles Triangle)
80 + 40 + x = 180 (Triangle Sum Theorem)
Starting with angle 1, which list contains all the angles that are congruent for these parallel lines.
1,4,5,8 (Vertical, Corresponding)
1,2,5,6 (Straight angle, Corresponding)
1,3,5,7 (Corresponding)
Which option has the correct set up?
tan 61 = x/18
sin x = 61/18
cos 61 = 18/x
What is the correct set up to find x?
sin 28 = x/19
cos x = 19/28
tan 19 = 28/x
What is the correct set up to find x?
tan x = 8/45
tan 45 = x/8
tan 45 = 8/x
Using these similar triangles, find the missing measure for angle B
45o
180 - 45 = 135o
45 x 12/18 = 67.5
What is the value of x?
