Reika [66]

Answer: y=2x+8

Step-by-step explanation:

(2,12)=(x1,y1)

(-7,-6)=(x2,y2)

(y2-y1)/(x2-x1)=(-6-12)/(-7-2)=-18/-9=2=m

y=mx+b

y=2x+b

insert (2,12) to y=2x+b

12=2*2+b

12=4+b

8=b

y=2x+8

A bit stuck on how to do this

Helen [10]

Answer:

x = 40°

Step-by-step explanation:

Two sides are the same length, so the angles opposite them are the same size.

The sum of the angles = 180°. One angle is 100°, so the sum of the remaining two angles is 80°.

Since the remaining two angles are congruent, each is 40°.
