Suppose ABC is a right triangle with sides a, b, and c and right angle at C. Find the unknown side length using the Pythagorean
theorem and
then find the values of the six trigonometric functions for angle B.
a = 9, C = 41
The unknown side length bis
(Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
1 answer:
Answer: b = 40
sin B = 
cos B = 
tg B = 
sec B = 
csc B = 
cot B = 
Step-by-step explanation: If the right angle is at C, then the hypothenuse is side c = 41.
Using Pythagorean Theorem:
hypotenuse² = side² + side²
41² = 9² + b²
b = 
b = 40
The side b length is <u>40</u>,
The trigonometric functions of a right triangle are:
1) Sine =
sin (B) = 
Sin(B) = 
2) Cosine =
cos (B) = 
cos (B) = 
3) Tangent = 
tg (B) = 
tg (B) = 
4) Sec = 
sec(B) = 
sec(B) = 
5) Cosecant = 
csc(B) = 
csc(B) = 
6) Cotangent = 
cot(B) = 
cot(B) =
