Answer:

x = 110

Step-by-step explanation:

all angles of the triangle MUST add up to 180 degrees.

45 + 65 = 110

180 - 110 =  70

since x is sittling on a 180 degree angle, the sum of 70 and x must equal 180 too

180 - 70 = 110

Answer:

70°

Step-by-step explanation:

we know that the angles in a triangle are equal to 180° and that a straight line has 180°.

180-(65+45)=110

this equation should give us the angle opposite x(the supplementary angle)

180=the sum of the angles on a straight line so

180-110=70

A bike is bought for $1200 and sold 10 months later for $940.
Stolb23 [73]

Value

Depreciation is defined as the reduction in value of an asset over time. In this case, value reduction is due to wear and tear of an equipment (bicycle).

a. The depreciation value would simply be the difference in initial and salvage value divided by time in years.

Depreciation = (Initial value – Salvage value) / Number of years

b. Substituting the given values into the equation where:

Initial value = $1200

Salvage value = $940

Number of years = 10 months = 10/12 years

Calculating:

Depreciation = ($1200 - $940) / (10/12 years)

Depreciation = $312 / year

or

<span>Depreciation = $26 / month</span>
