3 inches i agree too 2020
Answer:
The answer to the is the first one: O x< 22.5; Sam hasa maximum of 22.5 minutes left to finish running.
10.5 + 22.5 = 33
Answer:
The slope is 2
Step-by-step explanation:
The formula to find slope is y2-y1/x2-x1
Plug in the numbers and you get: 5-3/1-2
The result of that is -2/-1 which can be simplified to 2
Answer:
x = 52.2 degrees
Step-by-step explanation:
In this question, we are to
calculate the value of the angle x
Now the first thing to identify is that what we have is a right angled triangle as one of the angles is 90 degrees
This means that we can employ the use of trigonometric identities to calculate whatever we want to calculate.
The question now is which trigonometric identity is the correct one to use
To answer this, we need to be sure of the sides we were given. Looking at the diagram we have one side facing the 90 degrees angle and the other side facing the angle x itself.
The one facing the angle given is the opposite while the one facing the angle 90 is the hypotenuse
So the trigonometric identity to use is the one that links the opposite and the hypotenuse
This is the sine
mathematically;
sine of an angle = length of opposite/length of hypotenuse
In this case
sine x = 6.4/8.1
sine x = 0.7901
Thus;
x = arc sin 0.7901
x = 52.2 degrees
Answer:
13
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 12^2 + c^2
25 + 144 = c^2
169 = c^2
<em>Square root both sides</em>
c = 13
