I have no clue how to do this could someone explain

35 degrees

Step-by-step explanation:

Since all the angles combined equal 180 degrees, you can already subtract 55 from it and then the 90 degrees from the angle ABC. After that subtract 180-145=35

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

14

step-by-step explanation:

14 x 3 = 42
