Find the distance between -4.3 and 7.5 on a number line.
distance:

11.8

Step-by-step explanation:

To find the distance between two numbers, one has to take the absolute value of the numbers and add it up. The absolute value of a number is its distance from zero (hence always a positive value).

|-4.3| + |7.5|

4.3 + 7.5 = 11.8

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

i those same problems in math and dont know how to do them
