Express the radical using the imaginary unit, i

Mathematics
1 answer:
Kipish [7]3 years ago
8 0

Answer:

7i.

Step-by-step explanation:

Note : The given expression must be \sqrt{-49}.

We have to write this radical value in the imaginary value.

The given value can be rewritten as

\sqrt{-49}=\sqrt{49\times (-1)}

\sqrt{-49}=\sqrt{49}\times \sqrt{-1}    [\because \sqrt{ab}=\sqrt{a}\sqrt{b}]

\sqrt{-49}=7\times i    [\because \sqrt{-1}=i]

\sqrt{-49}=7i

Therefore, the required expression is 7i.

Determine the measures of angles C and D.<br>​
Morgarella [4.7K]

Answer:

c = 40 and d = 76

Step-by-step explanation:

this is going to take me a long time to explain but here we go

so you need to do 180 - 116 and get 64.

then create a equation that is like this 7y + 6 + 4y + 64 = 180

when you solve it you get y = 10

then plug in 10 in for y in 4y. and you get 40 for c

do the same for d and you will get 76

pls mark me brainleist because i didnt waster your time.
