In right triangle XYZ, the tangent of acute angle X is 4. What is the secant of angle X?

Answers

Answer:

The secant of angle x; sec x = √17

Step-by-step explanation:

Here, given the tangent of an angle, we want to find the value of the secant

Mathematically;

sec^2 x = 1 + tan^2 x

This is from trigonometric identity

Thus;

sec x = √(1 + tan^2 x)

According to the question;

tan x = 4

So tan^2 x = 4^2 = 16

Thus;

sec x = √1 + 4^2

sec x = √17

a car wheel has a 14 inches radius. through what angle does the wheel turn when the car rolls forward 2 ft???? ...?

Answers

arc length = rad * angle2 ft = 14 inch * angle2*12 inch = 14 inch * angleangle = 24/14 inch = 12/7 radiansthis angle is in radianswe need to convert it into degress so for conversion, (12/7)*(180/pi)solve it and u get 1080/11 deg or 98.2 deg

Which expression correctly represents the product 12(8 5) after applying the distributive property?

Answers

Answer:

Distributive Propety

Step-by-step explanation:

We are given the following information in the question:

Distributive Property:

It helps us to perform complicated maths problem easily.

The distributive property allows us to multiply a sum by multiplying each addend separately and then adding the products separately.
$a* (b+c) = (a* b) + (a* c)$
Example:

$5* 8 =5* (2+6) = (5* 2) + (5* 6) = 10 + 30 = 40$

The given problem can be solved as:

$12* (8+5)\n=(12* 8) + (12* 5) \n= 96 + 60\n=156$

u don't use the distributive property here order of operations says do operations in parentheses FIRST 12(8 +5) = 12(13) = 156 12(8 +5) = 12(8) +12(5) = 96 +60 = 156
