Answer:

Angle DCE is a central angle so it's equal to the arc facing it, which is DE, which is given as 116. So angle DCE= 116°

Angle EDF is an angle between a tangent line, DF, and a secant line, DE. So its measure is equal to half of the arc it surrounds, which is arc DE. 116/2= 58°. Angle EDF=58°.

Answer:

$360\ cm^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the bottom rectangle</u>

$A = l * w$

$A = 10\ cm * 12\ cm$

$A = 120\ cm^2$

<u>Step 2: Determine the area of the back rectangle</u>

$A = l * w$

$A = 10\ cm * 5\ cm$

$A = 50\ cm^2$

<u>Step 3: Determine the area of the top rectangle</u>

$A = l * w$

$A = 10\ cm * 13\ cm$

$A = 130\ cm^2$

<u>Step 4: Determine the area of the triangle</u>

$A = \frac{h*b}{2}$

$A = \frac{5\ cm * 12\ cm}{2}$

$A = \frac{60\ cm^2}{2}$

$A = 30\ cm^2$

<u>Step 5: Determine the surface area</u>

$120\ cm^2 + 50\ cm^2 + 130\ cm^2 + 2(30\ cm^2)$

$360\ cm^2$

Answer: $360\ cm^2$
