Answer:

Step-by-step explanation:

I really hope that solving a few trig questions can forestall death. That would be a really easy way to get rid of the C 19 restrictions and a myriad other diseases. BETTER LIFE THROUGH MATH will be our motto.

11) tan45 = x/13 x = 13

cos45 = 13/y y = 13√2

12) sin30 = 4/x x = 8

tan30 = 4/y y = 4√3

13) sin60 = 21/x x = 21(2/√3) = 42/√3

y = xcos60 = (42/√3)(1/2) = 21/√3

14) cos45 = x/22 x = 22/√2

sin45 = y/22 y = 22/√2

15) Height = 24sin30 = 12

cos 45 = 12/x x = 12/√2

tan45 = y/12 y = 12

cos30 = z/24 z = 24(√(3)/2) = 12/√3

Answer:

x=45

Step-by-step explanation:

the sum of straight angle=180

2x+45+x=180

3x=180-45

3x=135

x=135/3=45

Answer:

The slope of the line representing the linear function f(x) is determined as $-\frac{1}{2}$ . The function f(x) is decreasing because the slope is less than zero, i.e., m<0.

Step-by-step explanation:

A linear function f(x) is given with two points, (2,3) and (0,4) lying on the line representing f(x).

It is asked to determine the slope of the line and state if the function is increasing or decreasing. of the value of the slope obtained.

Step 1 of 1

Determine the slope of the line.

The points as given in the question are (2,3) and (0,4). Now, the formula for the slope is given as

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

So, substitute $4 \& 3$ for $y_{2}$ and $y_{1}$ respectively, and $0 \& 2$ for $x_{2}$ and $x_{1}$ respectively in the above formula. Then simplify to get the slope as follows, $m=\frac{4-3}{0-2}$\\ $m=\frac{1}{-2}$\\ $m=-\frac{1}{2}$
