b)5cosTHETA=2
c)4tanTHETA=6
d)8cscTHETA=10
THANK YOUUUU
Wouldn't it be faster just to put each of those into the equation and see if they satisfy it?
2.In triangle ABC, B=65 degrees, b=2 and c=12. How many triangles are possible?. Draw a line segment of length 12. At one end of it draw a line at angle 65 degrees. Draw a circle having the other end as a center and radius 2. How many times does the circle intersect the line?Don't you have a calculator?3. Find sin29°42' to four decimal places_
4. Find sec17°8'49" to four decimal places
sin THETA= 4/7, cos THETA = 2/5, tan THETA= 6/4, csc THETA= 10/8. Use your calculator to find each of those and decide which is largest.5.Which of the following statements would give the largest value of theta if theta was less then 90°?
