sin∅ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

∅ = 40°

opposite leg of angle = 50 ft

hypotenuse = x ft

Step 2: Solve for x

Substitute: sin40° = 50/x
Multiply x on both sides: xsin40° = 50
Divide sin40° on both sides: x = 50/sin40°
Evaluate: x = 77.7862
Round: x = 77.8 ft

Explanation :
First distribute it which is
=> w= 6a+3b -4
Then start moving the numbers to the left

Hamdan says that when you add fractions with the same denominator, you can add the numerators and keep the same denominator. Is

Elina [12.6K]

Answer:

Yes, Hamdan is correct.

Step-by-step explanation:

Let the two fractions are q/r and s/r.

Here, the denominator is same for both the fractions.

So, as we add them, add the numerators and the denominators remains same.

$\frac{q}{r}+\frac{s}{r}\\\\=\frac{q + s}{r}$

For example

$\frac{3}{5}+\frac{4}{5}\\\\=\frac{3 + 4}{5}\\\\=\frac{7}{5}$

So, Hamdan is correct.

Arrange the list of numbers in increasing order.. . 2/5, 4/9, 3/7

Allushta [10]

The numbers given in the question are 2/5, 4/9 and 3/7. We have to take them to decimal form for arranging the numbers in increasing order.
2/5 = 0.40
4/9 = 0.44
3/7 = 0.43
Then, the increasing order of the numbers would be
2/5 < 3/7 < 4/9
I hope the answer has helped you.
