Cos 52 = 0.6157
sin 42 = cos 48 = 2/3 (because 42 + 38 = 90 - complementary angles)
if tan 20,5 = 3/8 then tan 69.5 wil = 1 / 3/8 = 8/3
Answer:
(x,y) = (0,0)
Step-by-step explanation:
Let both as equation (1) and (2)
put equal both sides -x = -7x
-x + 7x = 0
6x = 0
x = 0
put it in 2nd equation
y = -7(0)
y = 0
Answer:

Step-by-step explanation:
<u>Step 1: Subtract m from both sides
</u>


<u>Step 2: Divide both sides by -1
</u>



Answer: 
Answer:
≈ 39.7ft
Step-by-step explanation:
The Pythagorean theorem:

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)
First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.


To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

≈ 39.7ft
