Alisiya [41]

Answer:

A. The value of x is 5

B. The length of each side is 20!

Step-by-step explanation:

For part A., We can determine x by setting these equations to equal each other (as we know that all sides of a square are equal)! See below for how to:

$4x = 2x +10\\2x = 10\\x=5$

For part B. sub x for 5 to get the side length of one side...

$4(5) = 20\\2(5) +10=20$

We already know that all sides are equal, so the side length of each side is 20!

Tan²Ф+sec²Ф=3 can someone solve this by finding all answers as the nearest whole degree

Stels [109]

Recall that

tan²(x) + 1 = sec²(x)

for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)

Then

tan²(Φ) + sec²(Φ) = 3

tan²(Φ) + (tan²(Φ) + 1) = 3

2 tan²(Φ) + 1 = 3

2 tan²(Φ) = 2

tan²(Φ) = 1

tan(Φ) = ±√1

tan(Φ) = 1 or tan(Φ) = -1

Φ = tan⁻¹(1) + n 180° or Φ = tan⁻¹(-1) + n 180°

Φ = 45° + n 180° or Φ = -45° + n 180°

The first family of solution is the set of angles

{…, -315°, -135°, 45°, 225°, 405°, …}

and the second family is the set

{…, -405°, -225°, -45°, 135°, 315°, …}

(showing the solutions for n = -2 to n = 2)

You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that

Φ = 45° + n 90°

If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then

Φ = 45°, 135°, 225° or 315°

Simplify this expression

luda_lava [24]

7 and 21 can cancel leaving a 3 on the bottom. one m can cancel from the bottom and the top so that leaves you with m^3 n^4/3
