Answer:
first one: 53°
Second one: reflective property of congruence <-(I'm not sure on this one but it seems like it)
Step-by-step explanation:
First one:
The measure of every triangle is 180°
we have to find that missing angle
so 180-53-74=53°
If its harder to understand you can make angle E x and solve 180=x+53+74
For the second one:
The reflexive property of congruence states that any geometric figure is congruent to itself.
This means that even same line segments and be congruent because of this property.
I hope this helped
15 red, 13 white, and 10 blue. I divided 38 by three and just sorta guessed from there if that makes any sense :P hope I helped!

The two lines in this system of equations are parallel
Step-by-step explanation:
Let us revise the relation between 2 lines
- If the system of linear equations has one solution, then the two line are intersected
- If the system of linear equations has no solution, then the two line are parallel
- If the system of linear equations has many solutions, then the two line are coincide (over each other)
∵ The system of equation is
3x - 6y = -12 ⇒ (1)
x - 2y = 10 ⇒ (2)
To solve the system using the substitution method, find x in terms of y in equation (2)
∵ x - 2y = 10
- Add 2y to both sides
∴ x = 2y + 10 ⇒ (3)
Substitute x in equation (1) by equation (3)
∵ 3(2y + 10) - 6y = -12
- Simplify the left hand side
∴ 6y + 30 - 6y = -12
- Add like terms in the left hand side
∴ 30 = -12
∴ The left hand side ≠ the right hand side
∴ There is no solution for the system of equations
∴ The system of equations represents two parallel lines
The two lines in this system of equations are parallel
