The correct answer for the given statement above would be TRUE. Dimensional analysis is a method of problem solving that often uses conversion factors. It a technique of problem solving wherein it uses the fact that any expression or number can be multiplied by one without its value changing. It is also known as the Factor-Label Method.
Answer:
Step-by-step explanation:
Later area of Pyramid = 2 * 1/2 * 9 * 12.3 + 2*1/2*11*11.9
= 9*12.3 + 11*11.9
= 110.7 +130.9
= 241.60 sq.feet
Answer:
-2
Step-by-step explanation:
you would go to wear your line crosses you y-axis, which is the vertical one
so it crosses at -2
Answer:
∠ECD is 110°
Step-by-step explanation:
For a cyclic quadrilateral,
∠ABC + ∠AEC = 180°
Therefore ∠AEC = 180° - 45° = 135°
∠CAE + ∠ACE + ∠AEC = 180° (Angles in a triangle)
Therefore ∠CAE = 180 - 20 - 135 = 25°
∠CAE = ∠CDA = 25° (Base angles of isosceles triangle ΔCAD)
∠CED + ∠AEC = 180°(Sum of angles on a straight line)
Therefore ∠CED + 135° = 180°
∠CED = 180° - 135° = 45°
∠ECD + ∠CED + ∠CDA = 180°
Therefore ∠ECD = 180° - (∠CED + ∠CDA)
∠ECD = 180° - (45° + 25°) = 110°
Therefore, ∠ECD = 110°.
