If an angle is a right angle, its measure is 90.
If an angle measure is 90, the angle is a right angle.
The answer is:
Both statements are true.
This is the biconditional.
An angle is a right angle if and only if its measure is 90°.
Other types of angles:
Acute angle - less than 90°
Obtuse angle - more than 90° but less than 180°.
Straight angle - exactly 180°
Reflex angle - more than 180°
For 7 to 9, substitute each answer in to the two equations.

Answer:
12 miles per hour
Step-by-step explanation:
Let her normal rowing speed be x
Also note the formula D = RT, where d is distance, R is rate(speed) and T is time
On windy day, her speed is x + 4
On against wind return, her speed is x - 4
With wind, she can go 48 miles in same amount of time when she goes 24 miles against wind. This can be written as:
48 = (x+4)T
24 = (x-4)T
We can write each equation in terms of T and equate both. So we have:
48/x+4 = T
24/x-4 = T
Thus,
Thus, Jaime's normal rowing speed is 12 miles per hour
