Answer:
Step-by-step explanation:
1. 30 degrees (vertical angles)
2. 60 degrees (complementary angles)
3. 150 degrees (supplementary angles and vertical angles)
4. 90 degrees (complementary angles)
Answer:
264
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
To simplify, find tan 90. Tan 90 isn't possible to find. Tangent is the value of Sine divided by Cosine. The sin 90 = 1. The cos 90 = 0. When you divide to find the tangent, it becomes 1 divided by 0. However, nothing can be divided by zero. The answer is undefined.
13 mph
using d=rt you can set up 2 equations
48=(r+3)t
30= (r-3)t
solving these both for t and setting them equal warrants
48/(r+3) = 30/(r-3)
and with cross multiplication and distribution you get
48r-144=30r+90
solving for r you get r=13
