Answer:
The height of the building is H = 11.65 yards
Step-by-step explanation:
Distance from the base of the building to the person = 50 yards
Angle of elevation = 25°
From Δ ABC
⇒ 
⇒ 
⇒ H = 11.65 yards
Therefore the height of the building is H = 11.65 yards
Expand out, this literally just wants you to multiply everything by -1.
so 7*-1 = -7
-c*-1 = c
thus putting them together to get -7+c which is just c-7
Answer:
A) 78
Step-by-step explanation:
The given sequence is an arithmetic sequence.
Here A1 = -6, common difference = (3/2)
nth term An = a1 + (n -1)d
A57 = -6 + (57 -1)3/2
= -6 + (56)*3/2
= -6 + 28*3
= -6 + 84
A57 = 78
Thank you.
