Answer:
total ground and wall angle is 90°
beam angle with ground= 51
beam angle with wall =39
because total angle=angle with ground + angle with wall
angle with wall=total angle-angle with ground
angle with wall= 90-51=39
All you have to do is take the size for every cereal, divide it with its price and you should get your answer as cents. then compare them all and see which one has the lowest price.

Step-by-step explanation:
Answer:
$6.30
Step-by-step explanation:
First, get the volume of the cereal box with the equation V = lwh.
V = 7(3)(10) = 210 cubic inches
Since it costs $.03 per cubic inch, multiply this cost by the volume to get the total cost to fill the box.
.03(210) = $6.30
the answer is 63 because 63*2=126 and 126+54=180 and all triangles add up to 180
