Answer:

Step-by-step explanation:

question no . 5

ratio of angle L

take angle as reference angle

using cos rule

cos L = base / hypotenuse

= 4/5

ratio of angle N

take angle N as reference angle

using sin rule

sin N = opposite / hypotenuse

= 4/5

for measure of angle L

cos L = 4/5

cos L = 0.8

L = $cos^{-1}(0.8)$

L = 36.9

for meanure of angle N

sin N = 4/5

sin N = 0.8

N = $sin^{-1}(0.8)$

N = 53.1

<h2>Answer:</h2>

<h2>Step-by-step Explanation:</h2>

<h3>(a) angle L ratio: cosL = 4/5 </h3><h3> angle N ratio: sinN = 4/5</h3><h3>(b) m angle L = cos ^-1(4/5) = 37° </h3><h3> m angle N = sin ^-1(4/5) = 53° </h3><h3>(c) m angle L + m angle N = 90° </h3>

How do you estimate 175.32 ÷ 3 =

geniusboy [140]

Answer:

≈ 58

Step-by-step explanation:

Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.

Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.

You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.

_____

The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.

Please help me with this!!

Step-by-step explanation:

To find the y-coordinate points we need to evaluate the function for all the $x$ values in the table. In other words, we need to replace $x$ with each value in our given function and simplify.
