The measure of angle 2 is 
Explanation:
Given that
and
are complementary angles.
Also, the measure of angle 1 is 
We need to determine the measure of 
Since, we know that the complementary angles add up to 90°, then the angles
and
add up to 90°.
Thus, we have,

Substituting the value of
in the above expression, we have,

Subtracting both sides by 76°, we get,

Simplifying, we have,

Thus, the measure of angle 2 is 
Answer:
Son = 14
Father = 42
Step-by-step explanation:
Let son age be x
Father's age is 3x and x + 28
3x = x + 28
2x = 28
x = 28/2 = 14
Father's age is x + 28 = 42
QUESTION A
The probability of an event is calculated using the formula:

There are 4 nines in a standard deck of cards. Therefore, there are 48 cards that are not nines.
Since there are 52 cards, the probability is calculated to be:

The probability is 12/13.
QUESTION B
Odds in favor of a particular event are given by the number of favorable outcomes to the number of unfavorable outcomes. The formula is written out to be:

Since we have that the number of favorable outcomes is 48 and the number of unfavorable outcomes is 4, we have that the odds in favor are given to be:

The odds are 12 to 1.
Answer:
Yes
Step-by-step explanation:
<u>7^2 + 4x</u>:
Fill in for x :
7^2+4(2)
solve:
49+8
=57
<u>4x+(7 x 7)</u>:
Fill in for x:
4(2) + (7 x 7)
solve:
8+49
=57
Thus, the correct answer is yes
6:9, if you need more just simply find common ratios or simplify.
