Give the domain and range of this relation.

{(1,2), (2, 4), (3, 6), (4,8), (5,10)}

Domain: 1, 2, 3, 4 ,5

Range: 2, 4, 6, 8, 10

Step-by-step explanation:

The domain is the x coordinate in a set of (x,y) coordinates and the range is the y coordinate in a set of (x, y) coordinates

EX:

(1,3) (5,2)

Domain: 1,5

Range: 3,2

answer: 1 and 3

step-by-step explanation:

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°
