Answer: v = u= 
Step-by-step explanation:
v= cos45 * 4=
- Apply Pythagorean theorem
= 
We have u =
You apply the sum of interior angles formula ie. (n-2)180. n=number of sides
since a pentagon has 5 sides it will be (5-2)180=540.
now add everything. x-5+x-6+2x-7+x+2x-2=540.
Solve for x: 7x-20=540
7x=540+20
7x=560
x=560/7
x=80
Answer:
x=16
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(8+24) * 8 = x^2
32*8 = x^2
256 =x^2
Take the square root of each side
sqrt(256) = sqrt(x^2)
16 = x
Answer:
=−2xy+3x+2y
Step-by-step explanation:
this is what i get in calculating
The square root of 8 is 2.82842712475. You round to 2 decimal places and get 2.83
