To figure this out, use the acronym SOHCAHTOA to determine which trigonometric function to use.
8 is opposite to <R and 3 is adjacent to <R so we use tangent.
Set up the following equation: tan(x)=8/3
Find the inverse (aka. tan^-1): x=69.44
So your answer is <R=69.4 degrees
Hope this helped!
1 is C since the points are not equidistant from the edges of the angle
2: is A and E
Answer:
$7.67
Step-by-step explanation:
So if 8 pens cost $4.72, one pen would cost $0.59. 0.59 x 13 will be equal to 7.67.
Answer:
g=-12
Step-by-step explanation:
3+g=-9
-3 -3
g=-12
Answer:
D.
Step-by-step explanation:
All other equations have x or y to the power of one so they are linear. D. has x or y to the power of two, so it's not linear. Quadratics and any variable to the power of 2 and above is not linear (numbers on their own are also always linear, so ignore any powers on them)
