Answer:
A cable that weighs 6 lb/ft is used to lift 600 lb of coal up a mine shaft 500 ft deep. Find the work done. Show how to approximate the required work by a Riemann sum.
Step-by-step explanation:
Answer:
EY≅ 5.33 cm (nearest to tenth)
Step-by-step explanation:
Two triangles are said to be similar to each other if they have the same shape
(not necessarily the same size) and their corresponding sides are in
proportion
Given that,
AB = 12
DE = 8
BX = 8
ΔABC ∼ ΔDEF means that
- ∠A ∼= ∠D, ∠B ∼=∠E and ∠C ∼= ∠F.
- Further more, their corresponding sides are in proportion.
So,
12/8 = 8/EY
(by doing cross multiplication)
12EY = 8 × 8
12EY = 64
EY = 64 / 12
EY= 5.3333
EY≅ 5.33 cm (nearest to tenth)

Answer:
depends on what type of triangle it is but generally there are two formulas area of triangle is ½ × base × height and another one is heron's formula used for finding area of triangle it is applicable only when side of a triangle is given A =
