Markel has a discount card that reduces the price of his purchases at GameStop by 7%. If c represents the cost of Markel's purchases, which expression represents Markel's bill?

is the expression that represent Markel's bill.

Step-by-step explanation:

We are given the following in the question:

Discount card provides a discount of 7%.

Let c be the cost of Markel's purchases, then,

Discount given to Markel =

Markel's bill =

= Cost price - Discount

is the expression that represent Markel's bill.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
