Welcome
d the answer is 73 degrees
Area=1/2 times bas time height
given that area=10
height=5
find base
10=1/2 times base times 5
times 2 both siddes
20=base times 5
divide oth sides by 5
4=base
the base is 4m
Answer:
10√3m
Step-by-step explanation:
Given :-
- Angle of elevation = 60°
- Distance between man and pole = 60°
We need to find the height of the pole . We are given here base. Therefore using ratio of tan ,
=> tan 60° = p/b
=> √3 = h / 10 m
=> h = 10 m× √3
=> h = 10√3 m
It equals 0.0192727261287227 mathamatics
I will assume that the two equations are
1) y = -x^2 +2x + 4 and 2) x +y = 4
subtract 2 from 1 and you get
y -x - y = -x^2 + 2x + 4 - 4
-x = -x^2 +2x
x^2 -x -2x = 0
x^2 - 3x = 0
x(x-3)=0
x=0 and x - 3 =0
x=0 and x = 3
Then y = 4 - x
y = 4 - 0 and y = 4 -3
y = 4 and y =1
