Answer:
Step-by-step explanation:
Area of one triangular face = 0.5(base)(height) = 20 sq cm
Surface area = 4(20) = 80 sq cm
Isolate the variable y
Line a: 3y = x+6
y = 1/3x + 2
Line b: 3y = x+18
y = 1/3 x + 6
Line c: 3y = 2x+9
y = 2/3x +3
Explanation:
Lines a and b are parallel because they have the same slope of 1/3.
Answer:
∠ ACE = 40°
Step-by-step explanation:
The sum of the angles in a circle = 360°, thus
arc AE = 360° - (112 + 28 + 112)° = 360° - 252° = 108°
∠ ACE is half the difference of the intercepted arcs, that is
∠ ACE = 0.5( arc AE - arc BD) = 0.5(108 - 28)° = 0.5 × 80° = 40°
