Answer:
x ≈ 3.42
Step-by-step explanation:
Using the sine ratio in the right triangle
sin20° = =
( multiply both sides by 10 )
10 × sin20° = x , then
x ≈ 3.42 ( to the nearest hundredth )
8-6x+11+3x+4x-5=5+3×4

<u>Answer:</u>
The expected value of construction company is $30500.
<u>Solution:</u>
Given, A construction company is planning to bid on a building contract.
The bid costs $1,500 and has an 80% chance of being accepted.
If accepted, the company will receive $40,000 dollars.
We have to find the expected value.
We know that,
Expected value = probability amount gained by bidding – bid amount
Expected value = 80% x 40000 – 1500
Expected value = 0.8 x 40000 – 1500
Expected value = 32000 – 1500
Expected value = 30500
Hence, the expected value is $30500.
Answer:
Step-by-step explanation:
Sine theorem: in any triangle, the ratio between a side and the sine of the opposite angle is constant
In our case, for the left triangle,
Time to grab a calculator and crunch numbers. Double check your calculator is in degrees and not in radians (plug in sin 30°, if you're getting 0.5 you're good) and you will get
Same difference with the right triangle. With the same calculations
