Plz help will give brainliest Point X (2,8) and point Y (-3,4) are located on a coordinate grid. Which measurement is closest to the distance between point X and Y in units? If you need graph paper to help you with this question, raise your hand and ask your teacher. 8.7D *
1 point
7.2 units
6.8 units
7.6 units
6.4 units

Step-by-step explanation:

I don't know what 8.7D means.

Find the difference in the x- and y-coordinates.

difference of x-coordinates = -3-2 = -5

difference of y-coordinates = 4-8 = -4

distance = √((-5)²+(-4)²) ≅ 6.4 units

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°

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
