Answer:

DI = 38

Step-by-step explanation:

Δ EHC and Δ DIC are similar and ratios of corresponding sides are equal, that is

$\frac{DI}{EH}$ = $\frac{DC}{EC}$ , substitute values

$\frac{DI}{76}$ = $\frac{1}{2}$ ( cross- multiply )

2DI = 76 ( divide both sides by 2 )

DI = 38

X=32 because both equations are equal to 180 degrees (3x+22°+x+30°=180) just solve that equation and you’ll get your answer

Step-by-step explanation:

√121 - √-192 - √4 + √-48

= 11 - 192i - 2 + 48i

= 9 - 144i

= 9(1 - 16i).

Instructions: Use the ratio of a 30-60-90 triangle to solve for the variables.

Pepsi [2]

Answer:

$x=20$

$y=10\,\sqrt{3}$

Step-by-step explanation:

In the triangle we have the following trigonometric equations:

$tan(60^o)=\frac{opposite}{adjacent} \\\sqrt{3} =\frac{y}{10} \\y=10\,\sqrt{3}$

and also:

$cos(60^o)=\frac{adjacent}{hypotenuse}\\\frac{1}{2} =\frac{10}{x}\\x=20$
