Answer:
a) No
b)
Step-by-step explanation:
a)
If , we have that , and .
, so and are not complementary when
b)
If , , and form half a circle, that means they sum to .
We now need to solve for .
Plugging in for and gives .
Combining like terms on the left side gives .
Subtracting a and a from both sides gives .
This means that and we're done.
Answer:
Step-by-step explanation:
For any triangle, the Law of Sines is given by .
Using this, we can set up the following equation:
Solving, we get:
Since there are 180 degrees in a triangle:
*It is worth noting that there is more than one possible answer for the measure of angle B. Since , there may be up to two answers when using the Law of Sines to solve for an angle. In this case, there are two possible triangles given the information given, however, only one option is given in the answer choices.

Answer: x=30 (Sorry for wasting your time if the answer is wrong)
Step-by-step explanation:
I did it the lazy way
80-20=60
60÷2=30
(If this is completely wrong then again, sorry)
Answer: 60 batches
Step-by-step explanation:
Let the number of batches be x
If 1 batch = 1/4 = 0.25tsp
x batches = 15tsp
0.25x = 15
x = 15/0.25=60
