Answer:
35
Step-by-step explanation:
I think you set them equal to each other, so I think you would do 5x-54=3x+16 and you would get 35.i hope I helped!☺️
Height of the wall is 27 m.
<u>Explanation:</u>
Let the height of the wall = h
Length of the ladder = 9 m
Angle of elevation = 60°
Ladder rests at 9 m below a vertical wall.
So, length of the wall upto which the ladder rests = h - 9
We know,
Cos Ф = base/ hypotenuse
cos 60° = length of the ladder / height of wall upto which the ladder rests
So,
h - 9 = 18
h = 27
Therefore, height of the wall is 27 m
Hello
Answer:
The correct answer is B
Step-by-step explanation:
You just use the Distribuatd property to solve
You multiply 10 to all the varibles inside the parthense
Becasued y is equal to 7 you would do 10x7=70
then 10x8=80
and 70+80=150
and the answer says the primeter is 150 when y=7
Hope this helps

Seeing as it is a isosceles triangle, two sides are the same length as each other.
We have been given the base, at 24cm, the two other sides must be the base taken away from the perimeter;
96-24 = 72
Then because the sides are of equal length, you can divide 72 by 2 to get the final length of one of the side lengths:
72/2 = 36
The side lengths are 36cm
The base length is 24 cm,
Hope this helps! :)
