The first one! It is using the distributive or associative property!
Answer:
supplementary angles add up to 180 degrees and complementary add up to 90 degrees
Step-by-step explanation:
We know that
[the length of a circumference]=2*pi*r
for r= 4 units
[the length of a circumference]=2*pi*4--------------> 25.12 units
if a full circle (360°) has a length---------------------> 25.12 units
arc for an angle of 72 °---------------------------> X
X=72*25.12/360------------> 5.024 units
the answer is
<span>the length of the subtending arc for an angle of 72</span>° is 5.024 units
Answer:
135.42 square feet
Step-by-step explanation:
2 x triangle face +
2 x rectangular face +
1 x base = Surface Area
2 ( 1/2 * 3 * 4) +
2 ( 3.61 * 11) +
4*11 =
12 + 79.42 + 44 = 135.42 square feet
