2) Corresponding angles of parallel lines cut by a transversal are congruent.
3) Vertical angles are congruent.
4) Transitive Property. If angle 2 is congruent to angle 6 and angle 4 is congruent to 2, then angle 6 is congruent to angle 4.
Answer:
Obtuse and Isosceles
Step-by-step explanation:
Since there is an angle greater than 90 degrees (104 degrees) the triangle is obtuse. Since there are two congruent sides, the triangle is also Isosceles.
Answer:
i believe its 24
Step-by-step explanation:
D=2R
but idk sorry
Suppose

is even, i.e. there is some integer

such that

. Then

where

is just some other integer. Therefore

is odd, proving the contrapositive, and so the original statement is also true.
Answer:
133
Step-by-step explanation:
The two angles add to a straight line
PQR + RQS = PQS
3x-5 + x+1 = 180
Combine like terms
4x -4 =180
Add 4 to each side
4x -4+4 = 180+4
4x =184
Divide each side by 4
4x/4 =184/4
x =46
We want to find PQR
PQR = 3x-5
= 3*46 - 5
= 138 -5
= 133
