(x + 2)/2 = (x - 6)/10
5(x + 2) = x - 6
5x + 10 = x - 6
5x - x = -6 - 10
4x = -16
x = -16/4 = -4
x = -4
Answer: The volume of the rectangular room is 240 meters. I dont know how many cubic meters that is!
Step-by-step explanation:
V of rectangle = L x W x H so V= 10 x 6 x 4 so V= 240
x^2-6x<u>+9</u>= 7<u>+9</u>
(x-<u>3)</u>^2= 16
Answer:
Approximately 360.3
Step-by-step explanation:
△ABC, AB = BC and CH is an altitude.
Note in isosceles triangle the two base angle are equal.
And two sides are equal.
CH = 84 cm and m∠HBC = m∠BAC +m∠BCH
So yhe base angle = 50°
The length of tthe hypotenuse , lets cal it x
Sin 50 = 84/x
X = 84/sin 50
109.65 = x
For the The base
109.65²-84²=b²/4
141 = b
Perimeter = 2*109.65 + 141
Perimeter = 360.3
Approximately 360
Hypotenuse is the longest side of a right-angled triangle.
Given the dimesions of the right angle triangle is 6, 7 and 3, 7 which is the longest represents the hypotenuse
Hence, the hypotenuse is 7
