Answer:

AC = 2.96

Step-by-step explanation:

Use the trigonometric ratio cosine:

cosine = adjacent ÷ hypotenuse

cos(65°) = AC ÷ 7

cos(65) = \frac{AC}{7}

Multiply both sides by 7:

7(cos(65)) = AC

(Note: Set your calculator to degrees!)

And plug 7(cos(65)) into your calculator to get:

AC ≈ 2.96

Can you please show me the steps and solution to this problem?
ANEK [815]
M = - 7 - 3 / - 2 - 4
m = - 10 / - 6
m = 10/6
m = 5/3

y = 5/3x + c , (4,3)
3 = 5/3(4) + c
12 = 20 + 4c
4c = - 8
c = - 2
y = 5/3x - 2

What is the slope of the line parallel to the line whose equation is y+4x=7
ryzh [129]

Y+4x =7

Or y = -4x + 7

On comparing with point slope form

y = mx+c

We get m = -4 = slope of given line

As the required line is parallel to given line its slope is equal to -4
