You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
THE ANSWER FOR THIS IS G. 16
Answer:
Theta = 59 degrees
Step-by-step explanation:
Here, we want to get the value of the marked angle
To do this, we use the appropriate trigonometric ratio
From what we have,
The side 42 ft is adjacent the angle given
The side facing the right angle is 82 ft
The trigonometric ratio that connects the adjacent and the hypotenuse is cosine. It is the ratio of the adjacent to the hypotenuse
Cos theta = 42/82
theta = cos^-1 0.5122
theta= 59.189
To the nearest degrees, this is 59 degrees
First we need to find the slope of the function
The slope of a function is equal to
So now we plug this into the equation and find the slope (M will represent the slope)
So the slope is -3/2
Now we can use point-slope form.
Point slope form is represented by
So when we plug in our values we get
So the equation is
Y = -3/2X-7/2
