yeppp that's itttt
The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that a = 8.6 in, b = 13.9 in. and c = 16.5 in. Using cosine rule:
c² = a² + b² - 2abcosC
16.5² = 8.6² + 13.9² - 2(8.6)(13.9) * cosC
C = 91.2°
Also:
a² = b² + c² - 2bccosA
8.6² = 16.5² + 13.9² - 2(16.5)(13.9) * cosA
A = 31.4°
A + B + C = 180° (angles in a triangle)
31.4 + B + 91.2 = 180
B = 57.4°
The missing parts of the triangle ABC are A = 31.4°, B = 57.4°, C = 91.2°

Answer:
2. Weather forecasts are difficult to trust
Step-by-step explanation:
Words like thus are preliminar to a conclusion, that is, we use words like thus when we are going to conclude something.
For Example:
The New Englard Patriots have won 6 Super Bowls. Thus, the New England Patriots are a good NFL franchise.
The conclusion is that the Patriots are a good NFL franchise.
In this problem, we have that:
Thus, it is difficult to trust weather forecasts.
The conclusion is:
2. Weather forecasts are difficult to trust
Answer:
1.25 hours
Step-by-step explanation:
If you're going 60 miles per hour, that's exactly how much miles you travel in an hour if that is your constant speed you are going the entire time, so it is at least 1 hour and we know it's not 4500 hours and it cant be .8 hours or 135 hours, think of yourself going on a caride would it really take 135 hours ? No so its 1.25. Also multiply 60 by 1.25 and you get 75.
