Answer:
correct answer: A)8
Step-by-step explanation:
The only way you have of finding the length of the missing side is
to ASSUME that the lengths of all 3 of them form a Pythagorean
triple. You know that you can go ahead and do this when you see
the little red 'corner' drawn in one vertex of the triangle. Then you
know that the angle is a right angle, the triangle is a right triangle,
and the sides form a Pythagorean triple.
Then (missing side) = √( 1.7² - 1.5²)
= √(2.89 - 2.25)
= √0.64 = 0.8 .
Without that little red box corner-symbol, there would be no way.
You would not stand a chance.
Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.
If you're talking about in terms of "equations", then this would work
The answer is 165.6 and the next formula can describe why:
46% * 360 degrees
<span>.46*360=165.6 degrees
</span>It is very easy with this procedure and I know it can help you with similar exercises.
