Answer:
sin θ = 0.2426.
Step-by-step explanation:
The cot and cos are both negative in the second quadrant.
cot θ = 1 / tan θ = -4 so tan θ = -1/4.
θ = 165.96 degrees
sin θ = 0.2426.
First one is positive second one is negative third one is negative fourth one is positive and the last one is positive
Answer:
28 degrees
Step-by-step explanation:
Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.
Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.
Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.
Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.
62+90=152
180-152=28
Answer:
15 days.
Step-by-step explanation:
1 person : 4 bird houses : 3 days
1 person : 20 bird houses : ? days
from 4 bird houses to 20 bird houses, you multiply by 5.
this means you also have to multiply the days by 5
3*5=15
Jared will have to work for 15 days to make 20 bird houses.
Answer:
a. Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are
b. Theoretical Probability. Experimental Probability.
Use theoretical probability by counting the favorable outcomes and put that in a fraction above all possible outcomes.
Use experimental probability by comparing the number of times the event occurs to the total number of trials.
