Answer:

x=5

∠ABD = 33

∠A = 115

Step-by-step explanation:

Once again here are the properties of a trapezoid:

Opposite angles are congruent

Opposite side lengths are congruent

And here is a property of a triangle:

the measure of the angles add up to equal 180

Given this information we need to find

x, ∠ABD and ∠A

First lets find x

Remember opposite side lengths are congruent

Segment AD and segment BC are opposite side lengths ( which are congruent)

That being said we create an equation to solve for x

2x = 10

step 1 divide each side by 2

2x/2=x

10/2=5

we're left with x = 5

Now lets find ∠A

∠C and ∠A are opposite angles

so ∠C≅∠A

Because ∠C = 115 ∠A also = 115

Finally lets find ∠ABD

because ∠BDC and ∠ABD are opposite angles we can find the measure of ∠BDC and get the value of ∠ABD

ΔBDC is a triangle formed within the parallelogram

That being said we can find the measure of ∠BDC using the triangle angle rule (stated previously)

That the measures of the angles in a triangle add up to equal 180

So we can find the missing angle (∠BDC) by subtracting the given angles ( which have a measure of 32 and 115) from 180

∠BDC = 180 - 32 - 115

180 - 32 - 115 = 33

so ∠BDC = 33

Meaning that ∠ABD also = 33

A car costs$cents when new. It was sold for four fifths of its cost price. How much money was lost on the car.
REY [17]

The question is incomplete as the cost price isn't given. However, taking the cost price as x :

Answer:

Kindly check explanation

Step-by-step explanation:

Given :

A car costs$cents when new. It was sold for four fifths of its cost price. How much money was lost on the car.

Let :

Cost price when new = x

Cost price when sold = 4/5 * cost price when new

Cost when sold = 4/5 of x = 4x/5

Amount of money lost on the car = (Cost price of car when new - Cost of car when sold)

Hence,

Amount of money lost on the car = (x - 4x/5)

x - 4x/5 = (5x - 4x) / 5 = x / 5

To obtain the exact price, kindly input the omitted cost when new for x.
