Answer:
Let the three angles be 2x,9x & 4x
By the problem,2x+9x+4x=180
15x=180
x=180/15
x=12
there fore the angles are
2x= 2*12=24°
9x=108°
4x=48°
Step-by-step explanation:
Answer:
1/2 and - 1/2
Step-by-step explanation:
umm ok so for slope you do m = y2-y1/ x2-x1 which can probably be any point since they havent specified so we will do
A) L (-8,8) and (0,4)M
m= 4-8/0-8
=-4/-8
= 1/2
B ) now for b its asking for the certain points of
n and p
(4,2) N and (8,0) P
m= y2-y1/x2-x1 = 0-2/8-4= -2/4 = - 1/2 for ur slope
these should be right.
Answer:
