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) =
Answer: n= t+2/3
Step-by-step explanation: 3n-2+2=t+2
Step 1.) 3n= t+2
Step 2.) 3n/3 = t/3 + 2/3
Step 3.) n= t+2/3
