Answer:
< 1 = 125 degrees
< 2 = 55 degrees
< 3 = 125 degrees
< 4 = 55 degrees
< 5 = 125 degrees
< 6 = 55 degrees
< 7 = 125 degrees (given)
< 8 = 55 degrees
Step-by-step explanation:
1 and 3 are equal because they are vertical angles, therefore proving their congruence.
7 and 1 are equal because they're alternate exterior angles, which are congruent.
2 and 4 are vertical, which is congruent.
5 and 7 are vertical.
6 and 8 are vertical.
T = 60°
all interior angles of a triangle always add up to 180°. using this information we can divide 180 by 3 to get 60.
Answer:
x=4
Step-by-step explanation:
4x + 7y= 51
We replace y by 5 and determine x.
4x+7×5=51
4x+35=51
4x=51-35
4x=16
x=4
