Brooke and Lamont ran a half marathon broke finished in 1 hour 50 minutes Lamont finished in 100 minutes who has the faster time ?

Lamont

Step-by-step explanation:

Since there are 60 minutes in one hour, you take take away 60 minutes from the hundred and convert it into one hour.

100-60=40

As you can see, there are forty minutes left, so you add that to the hour, therfore, you know that Lamont ran for 1 hour and 40 minutes, which is faster than Brooke’s one hour and 50 minutes

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°
