Answer: 
Step-by-step explanation:

plugging in the values we know:

Therefore,






Answer:
a = 77°
Step-by-step explanation:
Two angles are complementary if their sum is 90 degrees.
Let us assume that the angle b is complement of a.
Given statement complement (complement (a)) = complement (b) = a
Complement (complement (77°)) = complement ( 13°) = 77°
The conclusion is obvious that this is the same angle.

Answer:
6.75 or 6 3/4
Step-by-step explanation:
First take the whole number and multiply that by 3.
2*3=6
Now, take the fraction and multiply that times 3.
1/4 as a decimal is 0.25. You can ignore the decimal point right now, but you have to remember it is there later.
So, whithout the decimal point, 25*3= 75.
Now, you add the decimal. The 75 is now 0.75, with the decimal.
Add the whole number and the decimal, and you have your answer!
6+0.75=6.75. As a fraction this is 6 3/4

Answer:
A. 5:6
Step-by-step explanation:
The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.
Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.
Therefore:
Scale factor = 25:30
Simplify
Scale factor of the smaller figure to the larger = 5:6
