Answer:
You need to take a screenshot of it becasue that doesnt make any snese
Step-by-step explanation:
you apply the concept of vertical angles and 180-degree angle
add 43 and 74 to get 117 now subtract it by 180 you get <u>63</u> for angle 1
now since angle 1 and 2 are vertical they are both <u>63</u>
<u></u>
now for angle 3 you add 63 plus 79 is 142 so, we subtract 142 by 180
therefore, angle 3 is <u>38</u> degrees
<u></u>
remember angles cannot be negative at all!
Answer:
y = 100°
Step-by-step explanation:
x = 40° (vertical angles are congruent)
y is an exterior angel of a triangle that has two opposite internal angles, x (40°) and 60°.
According to the exterior angle of a triangle, thus:
y = 40 + 60
y = 100°
