Angles 1 and 3, angles 2 and 4, angles 5 and 7, and angles 6 and 8. They are also congruent, because vertical angles are congruent.
Answer:
The triangle is 50,50 80
Step-by-step explanation:
The three angles of a triangle equal 180 degrees
We only want one 80 degree angle. That means the other two angles have to be the same, since it is an isosceles triangle. Call the other angle x
x+x+80 = 180
2x+80 =180
Subtract 80 from each side
2x+80-80=180-80
2x =100
Divide by 2
2x/2=100/2
x = 50
Each of the other angles in the triangle would have to equal 50 degrees
The triangle is 50,50 80
Answer:
Option C is correct
Step-by-step explanation:
In this question, we are asked to select which of the options have the same value as 7/3
We examine the options one urge other.
Option A
9/49; This is wrong as it cannot be divided further to yield while multiples
Option B
18/42; Dividing through by 6 will yield 3/7 which is not same as 7/3; This makes this option wrong too
Option C
42/18; dividing through by 6 will yield 7/3 which makes this option correct
Option D
49/9; This is a dead end as it cannot be divided further to give whole number multiples
You can think of this equation as

and thus apply the transformations to it as such



1) D = 2, C = +3
2) D = -12, C = -2
3) C = +6, D = 3
4) C = -7, D = -7
