The top of a ladder is resting against the edge of a roof. The ladder is 8.2 m long and makes a 19o angle with the house. How far away is the base of a ladder from the house (in cm to the nearest whole number)?
sin19 = x/8.2
x = (sin19)(8.2)
x = 2.67 m = 267 cm
cosx = 9/13
x = cos(9/13)
x = 0.9999o
cosx = 9/13
x = cos-1(9/13)
x = 46.2o
Is the following a right angle triangle?
NO
82 + 92 = 112
145 = 121
Which function would I use?
sin-1
Solve for x and y to the nearest whole number.

y = 17 in
Sun rays are shining past a tree and hit the ground at a 53o angle. If the tree casts a shadow of 6 m, How tall is the tree(to one decimal place)?
tan53 = x/6
x = (6)(tan53)
x = 8.0 m
sin20 = x/10
x = (sin20)/10
sin20 = x/10
x = (10)(sin20)
