Step-by-step Explanation:
Given:
∆WXY
m < X = 130°
WY = x = 31 mm
m < Y = 26°
Required:
Area of ∆WXY
Solution:
Find the length of XY using Law of Sines
X = 130°
x = WY = 31 mm
W = 180 - (130 + 26) = 24°
w = XY = ?
Multiply both sides by sin(24) to solve for x
(approximated)
Find the area of ∆WXY
(to nearest tenth).
Answer:
A) In 4 hours the tempature would both be the same
B) The tempature then would be 3 degreees Fahrenheit
Step-by-step explanation:
SO for the first step just make a list
In my format
x (hour): Coldspit and Frostberg in temperature
1st hour: -4.5 and 15
2nd hour: -2 and 11
3rd hour: 0.5 and 7
4th hour: 3 and 3
Answer:
The amount earned is 2,600
Step-by-step explanation:
In order to find the commission amount, start by multiplying the percentage by the amount sold. Then to find the total amount, add the flat rate.
30,000*.02 = 600
Then add the flat rate
600 + 2,000 = 2,600

Answer: 0.5</h3>
========================================================
Explanation:
The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.
We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.
This leaves sin(B)/b
We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.
The angle opposite side c is 15 degrees, so C = 15.
The lowercase letters represent side lengths, while the uppercase letters are angles.
--------------------------
We have enough to apply the law of sines to solve for side c.
sin(B)/b = sin(C)/c
sin(105)/2 = sin(15)/c
c*sin(105) = 2*sin(15) ............. cross multiply
c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)
c = 0.53589838486224
c = 0.5
Side c is roughly 0.5 cm long.
Make sure your calculator is in degree mode.
Answer:
Y = - 2/3 x + 3
Step-by-step explanation:
y = -2/3x+5/3
Slope = -2/3. .. parallel line has same slope
For (- 3 , 5)
Y intercept = y - my = 5 - ( (-2/3) x (-3) ) = 3
Y = slope x X + y intercept
Y = - 2/3 x + 3
