The measure of angle b is 83, and the measure of angle c is 42. what is the measure of angle d in degrees? a. 41 b. 45 c. 55 d. 125

Step-by-step explanation:

The sum of a triangle is 180 degrees. Since you already know two angles, the third one must enable the triangle to equal 180. You first add 83 and 42 together to get 125, and then subtract 125 from 180 to get 55 degrees as your answer.

55

Step-by-step explanation:

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)

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
