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!
The missing justification is the Subtraction property of equality.
This is because to get 1/3x=4, you need to subtract 3 from both sides.
That would be B, C and E.
A and D could be a rhombus.
Answer:
a = c + 16
Step-by-step explanation:
a = b + 12
b = c + 4
sub in value of b into 1st eqn.
a = c + 4 + 12
a = c + 16
