Answer:

<em> The value of ∠A = 67.98°</em>

Step-by-step explanation:

The right angled triangle is given as

Given ,

Value of AC = 3 units

Value of AB = 8 units

Value of ∠A = ?

By using Pythagoras theorem,

$AB^{2}$ = $AC^{2} +BC^{2}$

$8^{2} = 3^{2} + BC^{2}$

BC = $\sqrt{55}$

By using Cos A = AC/AB

A = $\cos^{-1}3/8$

A = 67.98°

<em> The value of ∠A = 67.98°</em>

Change the mixed numbers into simple fractions:
-9/4-(-67/8)
Find the common denominator and subtract:
$\frac{(-9*8)-(-64*4)}{4*8} = \frac{196}{32}= \frac{49}{8} =6 \frac{1}{8}$

So your answer is H
