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:
Perimeter is the distance around the outside of a shape. Perimeter is found by adding together the length of all a shape's sides.
P = a + b + c + d
p = 4 × a
p=2a+2b

Answer:
$815
Step-by-step explanation:
Given data
Principal= $500
Rate= 9%
TIme= 7 years
The simple interest formula is
A=P(1+rt)
substitute
A= 500(1+0.09*7)
A=500(1+0.63)
A= 500*1.63
A=$815
