Step-by-step explanation:
the perimeter is the easiest, really. we only need to add all side lengths. there is nothing else to the perimeter calculation.
so,
perimeter = 6.5 + 2.5 + 6 = 9 + 6 = 15 ft.
area is also relatively easy for right-angled triangles, because the sides that enclose the 90° angle, act also as height of the triangle to each other.
so, it is a half-rectangle, and we only need to multiply these 2 sides (not including the Hypotenuse) and divide this by 2.
area = 6×2.5/2 = 3×2.5 = 7.5 ft²
Answer:
w ≤ 19
Step-by-step explanation:
4w−16≤60
Add 16 to both sides.
4w−16+16≤60+16
4w≤76
Divide both sides by 4.
4w/4 ≤ 76/4
w≤19
You'll have to start off by finding the variables. Ex:
3(x + 3) - 2(x + 3)
As you can see here, the two similar variables are x. By using the distributive property, you will get this:
3x + 9 - 2x + 6
Next, you'll want to subtract the two variables, since 2x has a - in front of it:
1x + 9 + 6
or
x + 9 + 6
Then, you want to add the two numbers without the variable:
x + 15
Your answer is x + 15.
Hopefully that helped! :)
Sometimes, for it depends on the triangle. Take a right triangle, for instance. In a right triangle, the hypotenuse is always greater than the two legs. Therefore, you cannot label any side as the base, since the sides are different. In an equilateral triangle, on the other hand, all of the sides and angles are the same. Therefore, no matter which way you turn the triangle, every side is equal. In this sense it doesn't matter which side is labeled as the base. So, it really depends on the kind of triangle you're referring to.
