Let's see. What is a right isosceles triangle?
A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.
What is the formula for the area of an isosceles triangle?
When y = the identical side lengths of the triangle,
and A = area,
(y × y) ÷ 2 = A
Note: Remember to compute from left to right! :)
We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.
Now, we can plug-in our values!
(y × y) ÷ 2 = 128
(y × y) = 64
Now, we square root both sides!
y = √64
y = 8
The length of the identical sides of the triangle is 8 meters.
Answer:
GPA ≈ 2.67
Step-by-step explanation:
Grade points are weighted by credit hours:
GPA = ∑(grade points×credit hours) / ∑(credit hours)
GPA = (3×2 +2×4 +4×3 +2×3)/(2 +4 +3 +3)
= (6 +8 +12 +6)/12 = 32/12 = 2 2/3
GPA ≈ 2.67
Answer:
Step-by-step explanation:
s = n(a + 1)
n(a + 1) = s
a + 1 = s/n
a = s/n - 1
1: m
2: l , p
3: m, q
4: l
5: s m q r
8: l m
10: l m s
11: l m n
ik i said i was gonna do 1 - 10 but i just did what i knew :)
