Answer:

4/9

Step-by-step explanation:

First, you'll want to find the area of both squares. You just multiply the side by itself, so 6x6 and 9x9 gives you areas of 36cm² and 81cm². Put 36 over 81 to create your fraction/ratio, and then just simplify it down by dividing the numerator and denominator by 9 in this case.

x = r sin θ cos Ф

x² = r² sin² θ cos² Ф

y = r sin θ sin Ф

y² = r² sin² θ sin² Ф

z = r cos θ

z² = r² cos² θ

x² + y² + z²

= r² sin² θ cos² Ф + r² sin² θ sin² Ф + r² cos² θ

= r² sin² θ (cos² Ф + sin² Ф) + r² cos² θ

= r² sin² θ + r² cos² θ

= r² (sin² θ + cos² θ)

= r² √

Find the indicated missing angle. Round to the nearest angle.

sladkih [1.3K]

Answer:

The missing angle 'x' is 22.29°.

i.e. $x\:=\:22.29^{\circ \:\:}$

Step-by-step explanation:

Let 'x' be the missing angle of the triangle.

Using the formula

tan x = opp ÷ adjacent

tan x = 30 ÷ 72

tan x = 0.41

$x=\tan ^{-1}\left(0.41\right)$

$x\:=\:22.29^{\circ \:\:}$

Therefore, the missing angle 'x' is 22.29°.

i.e. $x\:=\:22.29^{\circ \:\:}$
