The diagram is attached below

Beaker 1: The measurement line is between 32  and 33. There are 5 lines between 32  and 33. Making line is between third line and fourth line(between 6 and 8). So 32.7

Beaker 2: The measurement line is between 30  and 40. We can clearly see the measurement line at 32. So its 32

Beaker 3: The measurement line is between 32.7  and 32.8. We have 10 small lines inbetween them. Measurement line at 4. So its 32.74

(b) the amount of water in each of 3 beakers are not same because we can measure the difference. But they are close to each other.

Please help!! law of sines and cosines related
pickupchik [31]

Answer:

as below

Step-by-step explanation:

to find the height of the pole recall the relationship of sin cos and tan to the triangle with this helpful mnemonic   SOH CAH TOA

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

we will need to solve two triangles and subtract  them.

one is the 15° one of the slope of the road and the other is the 57° one that is the angle of the sun. sooooo,

lets solve the 15° one first.  We are told that the adj side is 75'

since we know the angle and the adj side and we want to find the Opp side let's use Tan b/c it has all of those in it :)  

Tan(15) = Opp / 75

75*Tan(15) = Opp   ( I'll put my calculator to work for this )

20.096 = Opp

that's the height of the road to the bottom of the flag pole along that flag pole axis into the ground  

next lets solve the 57°  triangle in the exact same way

Tan(57) =Opp / 75

75*Tan(57) = Opp

115.4898 = Opp

the tall triangle is the one that goes all the way into the ground,  the small one is the one that is under the ground

so subtract the small one from the big one to find the height of the flag pole above the ground

115.4898-20.096 = 95.3938

so the flag pole is about 95.4 feet tall

:o that's pretty tall :

WHAT ARE THE THREE DIFFERENT TYPES OF ANGLES!!!!!!??
Vikentia [17]
<em>Hello there, and thank you for asking your question here on brainly.

<u>Answer: The three different types of angles are an acute angle, which is an angle that is an angle that measures from 1</u></em>° <em><u>to 89°. A right angle, that specifically measures to 90</u></em>°. <em><u>Finally, an obtuse angle that measures from 91° to 179°. An angle that also measures 180° is a straight line, and is called a straight angle. 

</u>Hope this helped you! ♥<u>
