Answer:

3\frac{7}{8}

Step-by-step explanation:

The given expression is 3\frac{1}{4} - (\frac{-5}{8})

We need to simplify the fractions.

Let's convert the mixed number 3\frac{1}{4} to improper fraction.

3\frac{1}{4} = \frac{4.3 +1}{4} = \frac{12 + 1}{4} = \frac{13}{4}

So, \frac{13}{4} -(\frac{-5}{8} )

= \frac{13}{4} +(\frac{5}{8} )

Now we have to find the least common divisor (LCD) of 4 and 8. So that we can simplify the fractions.

The LCD of 4 and 8 is 8.

So make the denominators as 8.

= \frac{13(2)}{4(2)} + \frac{5}{8}

= \frac{26}{8} + \frac{5}{8}

Now the denominators became the same. Now we can simplify the numerator and keep the denominator as it is.

=  \frac{26 + 5}{8}

=  \frac{31}{8}

Now we can convert this improper fraction to mixed number

= 3\frac{7}{8}

Analyze the diagram below and complete the instructions to follow.<br><br> Find a, b and c
Feliz [49]

Answer/Step-by-step explanation:

✔️Using trigonometric ratio, find b:

Reference angle = 45

opposite = 8

Hypotenuse = b

Thus,

Sin(45) = 8/b

b = 8/sin(45)

b = 8/(1/√2) (sin 45 = 1/√2)

b = 8 × √2/1

b = 8√2

✔️Find a using trigonometric ratio:

Reference angle = 60°

Hypotenuse = b = 8√2

Adjacent = a

Therefore,

Cos(60) = a/8√2

8√2*cos(60) = a

8√2*½ = a

4√2 = a

a = 4√2

✔️Find c using Pythagorean Theorem:

c² = b² - a²

c² = (8√2)² - (4√2)²

c² = 128 - 32

c² = 96

c = √96

c = √(16*6)

c = 4√6
