Answer:
8.65 miles
Step-by-step explanation:
The total of his short runs are 9.35 so you need to find out how many miles he has left till he reaches 18 miles.
The equation you can use is 9.35 + x = 18 x will equal the number of miles for the long run.
9.35 + x = 18
to isolate x you will subtract 9.35 from both sides.
you will get:
x = 8.65
8.65 miles
Step-by-step explanation:
sec x − cos x
Secant is the inverse of cosine:
(1 / cos x) − cos x
Find the common denominator:
(1 / cos x) − (cos² x / cos x)
Subtract:
(1 − cos² x) / cos x
Answer:
x ≈ 3.5 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin23° = 
= 
= 
( multiply both sides by 9 )
9 × sin23° = x , then
x ≈ 3.5 cm ( to 1 dec. place )
