If the angles are complementary, we have that:
- The measure of angle 1 is of 24º.
- The measure of angle 2 is of 66º.
-----------------
- If two angles are complementary, the <u>sum of their measures is 90º.</u>
- In this problem, we suppose that angles 1 and 2 are complementary, thus:

-----------------
- The measures of angle 1 and angle 2 are in a 4:11 ratio, thus:


-----------------
Considering 


The measure of angle 1 is of 24º.
The measure of angle 2 is of 66º.

Answer: 
Step-by-step explanation:
Since the general quadratic equation is,

Here the given table is,
x 1 2 3 4 5 6 7
y 5.9 8.9 13.4 20.1 30.1 45.1 67.7
By the graphing calculator,
a = 1.87024 ≈ 1.87
b= -5.15833 ≈ -5.15
c = 10.5429 ≈ 10.54
By putting the values of a, b and c,
The required quadratic equation is,

⇒ First Option is correct.
Answer:
Option C.
Step-by-step explanation:
The given expression is

We need to find the expression which is equivalent to the given expression.
The given expression can be rewritten as

The greatest common factor (G.C.F.) is 6. Taking out G.C.F., we get

Hence, the correct option is C.
The Answer is AOX
