ABC is a right-angled triangle atB. AB=(3x+2)cm and BC=2CM.GIVEN THAT THE AREA OF THE TRIANGLE IS 85CM SQUARE FIND THE VALUE OF X.
Say that the
height= 3x+2
base= 2
Area of a triangle equals 1/2 base times height
so...
(1/2) of the base is 1
and 1 times the height (3x+2) is 3x+2
Since the area equals 3x+2 and 85 you can set those numbers equal to each other to solve for x
3x+2=85
See if you can solve for x from this point
Just ask if you need any more help :-)
To solve the equation 3x + 2 = 85 for x, you can start by subtracting 2 from both sides of the equation:
3x + 2 - 2 = 85 - 2
This simplifies to:
3x = 83
Next, divide both sides of the equation by 3 to isolate x:
(3x)/3 = 83/3
This gives you:
x = 27.67
Therefore, the value of x is approximately 27.67.
