Answer:
A,
Step-by-step explanation:
Answer:
D) 5
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes.
The line: 
has a slope of 
as it is in y=mx+b form, where m is the slope, and b is the y-intercept.
Since the slope is , we see that the negative reciprocal slope is 
, as 
is the reciprocal (flip the numerator and denominator).
From here, we can use point slope form: 
, where 
is the point. In this case, (3, 1) is the point.
Thus, we have: 
as our final equation.
Simplifying: 
And: 
, which gives us the y-intercept to be 5.
Let me know if this helps!
Answer:
angle BAD = 180 -2x
angle BCD = x given
angle BCD is an inscribed angle
angle DOB = 2 (angle BCD)
angle BAD = 180 -angle DOB 2 tangent theorem
Answer:
15/15 aka 1
Step-by-step explanation:
9/15 and 2/5
keep the 9/15 and then denominator the bottom number has to be the same as the first one so multiply 5 times 3 to get 15 whatever you do to the bottom you have to do to the top so 2 times 3 equals 6.
9/15 and 6/15
9+6 equals 15
15/15 which then equals 1
