100.15 rounded to the nearest tenth

100.2

Step-by-step explanation:

nearest tenth = 1 decimal place

100.15

We look at the 5 and it can round 1 up

100.2

Step-by-step explanation:

To round up a number, we would round it up if it was above five and round it down if it was below.

However, since it is directly 5, we would round it up

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°

slope is 35 and 20 miles is the y-intercept.
