Answer:
m∠A = 33.948° or 0.5925 radians
Step-by-step explanation:
cos(A) = (b^2 + c^2 − a^2) / 2bc
cos(A) = (22^2 + 8^2 − 16^2) / 2*22*8 = 0.8295454545 or 73/88
m∠A = arccos(73/88) = 33.94792653
Answer:
x + y = 10
Step-by-step explanation:
The mean is calculated as
mean =
, thus
= 5 ( multiply both sides by 6 )
20 + x + y = 30 ( subtract 20 from both sides )
x + y = 10
Answer:
<h2>x =h-12y-2/4</h2>
Step-by-step explanation:
h = 4x +12y +2
h-12y-2=4x
<h2>thus x = h - 12y - 2 / 4</h2>
