2 consecutive even integers....x and x + 2
x + x + 2 = 66
2x + 2 = 66
2x = 66 - 2
2x = 64
x = 64/2
x = 32
x + 2 = 32 + 2 = 34
ur 2 integers are : 32 and 34

Answer:

- A pair of complementary angles is angles ACD and DCB.
Step-by-step explanation:
<u>Definitions</u>
- Two or more angles are supplementary if they add up to 180 degrees.
- Two or more angles are complementary if they add up to 90 degrees.
In the diagram which is attached below:
Angles ADC are BDC are on a straight line, and they add up to 180 degrees.
Therefore:

Furthermore,

A pair of complementary angles is angles ACD and DCB.
Sin = opposite/hypothenuse
Given opposite = 16
Hypothenuse = ?
Use Pythagorean theorem to find hypothenuse
12^2 + 16^2 = h^2
144 + 256 = h^2
h^2 = 400, h = 20
You know hypothenuse is 20
Opposite/hypothenuse
Solution: 16/20
Simplify if you need to (4/5)
