Answer:
D) 90 inches
Step-by-step explanation:
There are 36 inches in a yard (3 feet)
To find how many inches, multiply the numbers.
2.5 × 36
90 inches
Hello!
The length of side BC can be found by using the Law of Sines. This law states,
a / sin A = b / sin B = c / sin C.
Given:
Angle A = 51.2 degrees
Angle B = 60.3 degrees
Side AC (or B) = 21 cm
Side BC (or A) = ? cm
Let's plug in these values into the formula to find the missing side length.
a / sin (51.2) = 21 / sin (60.3)
a / sin (51.2) = 24.1759... (multiply both sides by sin(51.2)
a = 24.1759 · sin (51.2)
a = 18.841...
18.841 can be rounded to 19.
Therefore, the length of side BC is equal to 19 centimeters.
They are congruent because of the angles, which means the congruency reason should be SAS.
Basically, you have to do 755/12.5 That will give you your average per minute.
2 meters = 200 centimeters
