Answer:63 will be you answer this is how i got it so that is a right traingal wich equals 90 so 90-15-12=63 and you could do 90-12-15=63
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
We will use the 2 coordinates marked on the graph as the reference.
The coordinates are:
A(4,-2)
B(0,3)
We know that the standard form for equation of line is:
y = mx+c
where m is the slope of the equation
and c is the y-intercept.
Very clearly, the y-intercept is where the line intercepts the y line.
and in this case, y-intercept = c = 3.
Now we know that the equation of line is now
y = mx + 3
To find m, the slope, we can use the 2 above coordinates.
slope of line = 
(Note: There is a 2nd way to find the slope in this case, let me know if you are interested to find out.)
Equation of line: 
Therefore the answer is D.
Answer:
{π/4, 5π/4}
Step-by-step explanation:
Tan theta -1=0 could be rewritten as tan Ф = 1. The tangent function is 1 at Ф = π/4. As the period of the tangent function is π,
tan Ф = 1 will be true for Ф = π/4 + π, or (5/4)π.
The solution set is {π/4, 5π/4}.
0.78 converted to a percent would be 78%
False. A two-column proof is also known as a "Statement-Reason Proof", with the statement column on the left and the reason column on the right.
