Answer: well first you have to flip one of the fractions, so for example 7/24 x 48/35 which should give you an answer of 336/840. If you simplify this down you should get 4/10. Another way of double-checking or simplifying is by dividing 336 by 840 (which should give you 0.4) and dividing 4 by 10 (which should also give you 0.4). Hope this helps!
Step-by-step explanation:
Answer:
height of building,H = 5.5 ft + 105.2 ft = 111 ft to the nearest ft.
Step-by-step explanation:
in this question we have given angle of elevation=
when surveyor walks 50m farther from the base of the tower that time angle of elevation=
As shown in figure in triangle ABD
.............(1)
or h=2.74x
and in triangle ABC
...........(2)
put value of h in equation 2
we got,
therefore,
Height of the tower is,h=2.74\times 38.39ft
h=105.2ft
Therefore,
height of building,H = 5.5 ft + 105.2 ft = 111 ft to the nearest ft.
12x+6=5x
Answer: There is one solution to the given equation.
Step-by-step explanation: We are given to find the number of solutions to the following equation :
Since the given equation is linear in one variable x, so it will have only one solution.
The solution of equation (i) is given by
Thus, there is one solution to the given equation.
Answer:
The angle that the ladder made with the ground = 53.13010235°
Step-by-step explanation:
The ladder has a length of 10 ft and it leaned against a wall to form a right angle triangle. The height from the top of the ladder to the ground is given as 8 ft. The triangle formed from the illustration can be represented with the picture below.
The angle A is the angle the ladder made with the ground.
Length of ladder = c
height from the top of the ladder to the ground = a
The distance of the foot of the ladder and the wall = b
c = 10 ft
a = 8 ft
Using SOHCAHTOA
sin A = a/c
sin A = 8/10
sin A = 0.8
A = sin-1 0.8
A = 53.13010235°
