Answer:
Step-by-step explanation:
This is right triangle trig. The side opposite the x is 8, and the side adjacent to the x is 5. The tangent ratio uses those sides. We need to find what angle has a tangent of 8/5. To do this, make sure your calculator is in degree mode. Then hit "2nd" then tan and you will see tan with a little -1 and a parenthesis. Enter 8/5 and hit "enter" and you will get an angle measure of 57.9946. Rounded to the nearest degree this is 58 degrees. That's your answer!
The unknown side lengths are
Large triangle 10
Medium triangle 2
Small triangle 12/5 or 2.4
Step-by-step explanation:
EFD to ABC is 0.4 or 2/5
EFD to GHI is 0.24 or 6/25
ABC to GHI is 0.6 or 6/10
Answer:
Correct answers:
A. An angle that measures
radians also measures 
C. An angle that measures
also measures
radians
Step-by-step explanation:
Recall the formula to transform radians to degrees and vice-versa:

Therefore we can investigate each of the statements, and find that when we have a
radians angle, then its degree formula becomes:

also when an angle measures
, its radian measure is:

The other relationships are not true as per the conversion formulas
Answer:
no
