3/4 x -18 = 1/4 x -4
subtract 1/4 x from each side
3/4 x -1/4 x -18 = 1/4 x- 1/4 x -4
2/4 x - 18 = -4
add 18 to each side
1/2 x -18 + 18 = -4 + 18
1/2 x =14
multiply by 2 on each side
2* 1/2 x = 14 * 2
x =28
The area of a circle is πr^2
Area formula for the white region is π6^2
π6^2 = 36π
Subtract the area of the white region from the combined area
100π - 36π = 64π
Answer:
yes
Step-by-step explanation:
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) =
