NEED HELP I SUCK AT GEOMETRY (OFFERING 100POINTS)!!! best answer get brainlest
Andrej [43]

Answer:

g = 3.5

f = 78°

<u>Finding</u><u> </u><u>g</u><u>:</u>

25 is parallel to 8g - 3, so they are equal to each other.

25 = 8g - 3

28 = 8g

g = 3.5

<u>Finding</u><u> </u><u>f</u><u>:</u>

72° create a sum of 180° when adding to (f + 30) because they are supplementary.

72 + f + 30 = 180°

102 + f = 180°

f = 78°

Hope this helps!

What is the distance between the points (-4,-8) and (10,-8)?
ioda

Answer: 14

Step-by-step explanation:

Input Data :

Point 1  ( x A , y A )  = (-4, -8)

Point 2  ( x B , y B )  = (10, -8)

Objective :

Find the distance between two given points on a line?

Formula :

Distance between two points =  √ (x B − x A ) 2 + ( y B − y A ) 2

Solution :

Distance between two points =  √ ( 10 −  − 4 ) 2 + ( − 8 −  − 8 ) 2

=  √ 14 ^2 + 0 ^2

=  √ 196 + 0

=  √ 196 = 14

Distance between points (-4, -8) and (10, -8) is 14
