Using the law os cosines formula b^2 = a^2 + c^2 - 2*a*c*cos(B)

a = 17, b = 8, c = 16

8^2 = 17^2 + 16^2 - 2*17*16* cos(B)

64 = 289 + 256 - 544 * cos(B)

544*cos(B) = 289 + 256 - 64

544 * cos(B) = 481

cos (B) = 481/544

B = arccos(481/544)

B = 27.8 degrees

A book sold 31,500 copies in its first month of release. Suppose this represents 8.9% of the number of copies sold to date. How

kogti [31]

Answer:

35,393,258

Step-by-step explanation

$\frac{31,500}{x} =\frac{0.089}{100}$

$0.089x=3,150,000$

$x= 35,393,258.427$

Rounded to the nearest whole number, that is 35,393,258.

Find three consecutive odd integers such that the product of the second and the third integers is twenty-six more than three tim

Ilia_Sergeevich [38]

Step-by-step explanation:

first number=x

second number=x+2

third number=x+4

(x+2)(x+4)=3x+26

x(x+4)+2(x+4)=3x+26

x²+4x+2x+8=3x+26

x²+6x+8=3x+26

x²+6x-3x=26-8

x²+3x=18

x²+3x-18=0

you can use that to find the numbers

Find the diameter of the circle. Assume the leg of the triangle is tangent to the circle. Round any decimals to the nearest tent

Anvisha [2.4K]

Answer:

8.7 units

Step-by-step explanation:

Given is a right angled triangle (because the segment with 5 units length is tangent to circle. Tangent is perpendicular to RADIUS or diameter)

Let the length of the diameter be d units

By Pythagoras Theorem:

$d = \sqrt{ {10}^{2} - {5}^{2} } \\ = \sqrt{100 - 25} \\ = \sqrt{75} \\ = 8.66025404 \\ = 8.7 \: units$
