If you want to find cosP , since angles Z and P are 2 complementary angles then cosZ is the same as cosP so you say the cosP=sinZ=4/5 (property of 2 complement angles in a right triangle)
Answer:
<u>(7.5-2.1) /2</u>
<u>If the shortest side measures 2.1 m</u>.
<em>7.5-2.1 =5.4.</em> Then divide by 2 each side is 2.7m
Answer:
99/100
Step-by-step explanation:
First of all recall that

Now we we will try to apply that formula for
and
.
First rewrite 
Now

We want to simplify √(-48).
Note that
i² = -1 by definition.
Therefore

Answer: c.
