Answer:
p > 12, p = 12
Step-by-step explanation:
She said she scored more than 12. It could be equal too.
Term=7p
<span>coefficient=7</span>
Profit=selling rice-cost price
P(x)=2x-(0.25x+0.5)
P(x)=1.75x-0.5
2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
Answer:
1
Step-by-step explanation:
First, convert all the secants and cosecants to cosine and sine, respectively. Recall that
and
.
Thus:


Let's do the first part first: (Recall how to divide fractions)

For the second term:

So, all together: (same denominator; combine terms)

Note the numerator; it can be derived from the Pythagorean Identity:

Thus, we can substitute the numerator:

Everything simplifies to 1.
