Answer:
Step-by-step explanation:
since we can see that the lines are parallel
and we can see that the both are interior angles and when we sum up both angles we get 180
2x - 5 + 45 = 180
2x + 40 =180
2x = 180 - 40
2x =140
x = 140/2
x = 70
Answer:
length= 7m and breadth= 21m
Step-by-step explanation:
Perimeter=56m
Perimeter of a rectangle= 2(l+ b)
Dimensions in the ratio 1:3
1:3= 1x and 3x
Take length as 1x and breadth as 3x
2(1x+3x)= 56m
2(4x)= 56
8x=56
x= 56/8 = 7m
length= 1x= 7m
breadth= 3x= 3*7 = 21m

Answer:
x = -3
y = -11
Step-by-step explanation:
You want to substitute one of the y's
3x - 2 = 2x - 5
+2 +2
3x = 2x - 3
-2x -2x
x = -3
now that you have x, you need to substitute the x to get y
y = 3x - 2
y = 3(-3) - 2
y = -9 - 2
y = -11
or
y=2x-5
y = 2(-3) - 5
y = -6 - 5
y = -11
*they will both be the same no matter which equation you use
