Answer:

Step-by-step explanation:

$i^{12}= i^{2} *i^{2} *i^{2} *i^{2} *i^{2} *i^{2}$

Remember that $i^{2}=-1$

Plug it in:

$i^{12}= (-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2}$

$=1*1*1*1*1*1$

$=1$

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

$15 + $10 = $25

$25 + x > $100

Subtract $25 from both sides

x > $75
