Pythagorean theorem - please help

Mathematics
1 answer:
Artist 52 [7]2 years ago
3 0

answer:

x = 4\sqrt{2} or 5.6568

step-by-step explanation:

  • know the formula and plug in

formula: a^2 + b^2 = c^2

  • now plug in what we have
  • whatever the RIGHT ANGLE points to is the HYPOTENUSE or c
  • the other two sides are the "legs" or a and b

a^2 + b^2 = c^2

7^2 + b^2 = 9^2

49 + b^2 = 81

b^2 = 32

b = 4\sqrt{2}

  • in this case, b would be used as x

x = 4\sqrt{2} or 5.6568 (exact value)

A sector has angle 2.5 radians and perimeter of 18cm. find the radius of the sector
babunello [35]

Answer:

4 cm

Step-by-step explanation:

Perimeter = 18cm

θ = 2.5 radian

s = rθ, s = Arc length

Perimeter of Sector, P = arc length, s + 2r

Perimeter = rθ + 2r

r = Radius

18cm = r(2.5) + 2r

18cm = 2.5r + 2r

18cm = 4.5r

r = 18 /4.5

r = 4

Find all numbers whose absolute value is 3 . If there is more than one, separate them with commas. If there are no such numbers,
adelina 88 [10]

Answer:

3, and -3

Step-by-step explanation:

Because absolute value is the distance away from zero, |3| and |-3| would both be 3 units away from 0. Be sure to have the negative on the inside if you're trying to make something positive, otherwise -|3| means that the absolute value of 3 would then become negative since the negative sign isn't a part of the absolute. hope this helps!
