Answer:
9:1or 1:9
Step-by-step explanation:
The original ratio is 36:4 but we have to simplify
36÷4=9
4÷4=1
so in the end of it you receive a ratio of 9:1 or 1:9
Answer:
She ran

Step-by-step explanation:
To find the answer you multiply the amount of races (9) by the length of each race (7/10 km).

Sin is opposite over hypotenuse, so sin(A) = 4/5. Cos its adjacent over hypotenuse, so cos(A) = 3/5

now, we know 7 of those angles are already 835°, so the last one must be 1080 - 835 = 245°.
Answer:
Option C) Angle 6 and 7 only
Step-by-step explanation:
Two angles are called supplementary when their measures add up to 180 degrees.
So here the angle supplementary to Angle 5 would be 6, since adding both would get us 180 degrees. Then there's angle 7 which would also give us 180 degrees when added to angle 5.
