Answer:
75º
165º
15º
255º
Explanation:
75º because half a circle is equal to 180º.
You know it is 165º because of the same reason.
You get the 15º from knowing that opposite angles are equal.
255º is a case of adding the angles.
Answer: 4/15
Step-by-step explanation:
-1/3 - -3/5
Two negative signs become positive so it's
-1/3+3/5
Taking the LCM as 15,
-1/3= -5/15
3/5= 9/15
-5/15 + 9/15
= (-5+9)/15
= (9-5)/15 ( just changing the order without changing the sign)
= 4/15
This is the simplest form
(If you need it in decimal form is 0.26666... or 0.267)

Answer:
SA = 108 ft^2
Step-by-step explanation:
The front and back faces are triangles with 4 ft base and 3 ft height.
The three sides are rectangles with dimensions 4 ft by 8 ft, 8 ft by 5 ft, and 3 ft by 8 ft.
The surface area is the sum of the areas of the two triangles and the three rectangles.
SA = 2 * (1/2)(4 ft * 3 ft) + 4 ft * 8 ft + 8 ft * 5 ft + 3 ft * 8 ft
SA = 12 ft^2 + 32 ft^2 + 40 ft^2 + 24 ft^2
SA = 108 ft^2
