Answer: 122 ft and 12.77 m
Step-by-step explanation:
First question answer = 100/cos35 = 122.07 = 122 ft
Second question answer = 12/sin70 = 12.77 m

Answer:
(-3, -6)
Step-by-step explanation:
The scale factor multiplies each coordinate.
A' = 3A = 3(-1, -2) = (-3, -6)
The image of A is ...
A'(-3, -6)
|x+y| = |-8+(-13)| = |-8-13| = |-21| = 21
Answer:
B -⅓
Step-by-step explanation:
sinx = -3/5
Adjacent² = 5² - 3² = 16
Adjacent = 4
tan(x) = -3/4
-¾ = 2tan(½x)/[1 - tan²(½x)]
-3 + 3tan²(½x) = 8tan(½x)
3tan²(½x) - 8tan(½x) - 3 = 0
tan(½x) = 3, -⅓
