Answer:
Point R
Step-by-step explanation:
Its the farthest away from the majority
Answer:
Yes
Step-by-step explanation:
X=-5-3y
If we take X to the other side and -5 to the other side then it becomes
3y=-5-X
So both the equations are same
so they have the same answer
Answer:
(a) 27 degrees (nearest degree)
(b) 17.9 m (to one decimal place)
Step-by-step explanation:
Wow, that's along ladder, perhaps for the firemen!
From diagram,
(a)
sin(x) = 9 / 20 = 0.45
x = arcsin(0.45) = 26.74 degrees
(b)
height of wall ladder reaches
h = 20*cos(x) = 20*cos(26.74) = 17.86 m
Step-by-step explanation:
Error = 7.7-7.4=0.3
% error= 0.3/7.7×100 % error= 3.89%
= 3.9% to the nearest tenth
