Answer:
C. 47 deg
Step-by-step explanation:
m<A = 180 - 94 - 39 = 47
m<D = m<A = 47
Answer: 12
Step-by-step explanation:
OKAYOKAY so what I did was 34 - 8 = 26
then 26 - 2= 24
THEN I divided 24 in to 2 equal parts and got 12 so that means y = 12
Hope that helps!!! :}
Answer:
x = -1/2 ( 3±sqrt(37))
Step-by-step explanation:
x^2 + 3x − 7 = 0
Add 7 to each side
x^2 + 3x =7
Using complete the square
Taking the coefficient of x
3
Divide by 2
3/2
Square it
(3/2)^2 = 9/4
Add this to each side
x^2 + 3x+ 9/4 = 7+9/4
( x+ 3/2) ^2 = 28/4 + 9/4
( x+ 3/2) ^2 = 37/4
Take the square root of each side
x+3/2 = ±sqrt(37/4)
x+3/2 = ±sqrt(37) / sqrt(4)
x+ 3/2 = ±sqrt(37) / 2
Subtract 3/2 from each side
x = -3/2 ±sqrt(37) / 2
x = -1/2 ( 3±sqrt(37))
Answer:
DM = 12
Step-by-step explanation:
I'm not very good with explaining but since MB is 12, vertex to the centroid which is M is 2/3 of the median, which is the line. So, since 12 is the 2/3 of the median, then DM would also be 12, since it's from vertex to centroid. Hope this helped.
