Angle B is also 54° because they are vertically opposite angles.
Now, you do 54+54=108 and then 360-108=252. (The angles should always add up to 360, so remember that) Because angles C and D are also vertically corresponding angles, they add up to 252, and each measure 126°
Answer:5π/12
Step-by-step explanation:
180°=π
75°=x
x=75π ➗ 180
x=5π/12
A= 2 WL+ 2 LH+ 2 HW.
W= width
L= length
H= height
