Answer:
x=3
Step-by-step explanation:
There's many ways you can begin this, I prefer getting rid of the fraction first.
Multiply both sides by 3/2 (yes, I switched it on purpose)
You get. . .
5x-6 = 9
To isolate the 5x, add 6 to both sides
5x = 15
Divide both sides by 5 and you get . . .
x=3
Answer:
100°= angle b(VERTICAL OPPOSITE ANGLE)
100°+x°=180°[co interior angle]
x=180°-100°
x=80°
Perimeter is the sum of all outside dimensions:
5 + 3 + 1 + 2 + 4 + 5 = 20cm
Area = (5 x 5) - (2*1) = 25 - 2 = 23 cm^2
Answer:
x = 6
Step-by-step explanation:
The area of a triangle is equal to the base times the height divided by two. In this case, the base is 6 (or x, it doesn't really matter) and the height is x (or 6, it doesn't matter). That means that the area of this triangle is equal to 6 * x divided by 2, which is also equal to 18. we can say that 6x/2 = 18, meaning that 6x = 36, so x = 6.
the answer this question is h=20 ft
