If sine theta equals three over four, what are the values of cos θ and tan θ?
cosine theta equals plus or minus square root of seven over four, tangent theta equals plus or minus two times square root of seven over seven
cosine theta equals plus or minus seven over four, tangent theta equals negative three over seven
cosine theta equals plus or minus square root of seven over 4, tangent theta equals plus or minus three over seven
cosine theta equals plus or minus seven over four, tangent theta equals negative one over seven

Part 1)

cosine theta equals plus or minus square root of seven over 4

Part 2)

tangent theta equals plus or minus three over square root of seven

or

tangent theta equals plus or minus three times square root of seven over seven

Step-by-step explanation:

we have that

The sine of angle theta is equal to

Is positive

therefore

The angle theta lie on the I Quadrant or in the II Quadrant

Part 1) Find the value of the cosine of angle theta

Remember that

we have

substitute and solve for cosine of angle theta

cosine theta equals plus or minus square root of seven over 4

Part 2) Find the value of tangent of angle theta

we know that

we have

substitute

tangent theta equals plus or minus three over square root of seven

Simplify

tangent theta equals plus or minus three times square root of seven over seven

what do you mean

have a great day
