please explain with work if possible

a)60°

b)BD=10

c)AB=20

d)100√3

Step-by-step explanation:

B

let's BD be x

according to the question

c)

according to Pythagoras theorem

a²+b²=c²

c=√a²+b²

c=√10²+(10√3)²

c=√100+300

c=√400

c=20

D)

the two triangles are congruent

so AC=2(10√3)

=20√3

as we know

area of a triangle =

½bh

=½×20√3×10

=10√3×10

=100√3

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
