Question

When sec theta=1.75, sin theta=√33/7 , please show me how you get this answer?

Answer 1

Sec is reciprocal of cos.
Sec 1.75 changed to improper fraction 7/4.
Cos theta is 4/7.
Sin is adjacent/hypotenuse
Use Pythagorean theorem to find the missing side of the triangle
4^2+b^2=7^2
b^2=49-16
b= sqrt33
Sin theta = (sqrt33)/7
