Answer:
Step-by-step explanation:
6) In rectangle, diagonals are equal.
KM = LN
6x + 16 = 49
6x = 49 - 16
6x = 33
x = 33/6
x = 5.5
7) 2x + 4 = 5x - 11
2x - 5x = -11 -4
-3x = -15
x = -15/-3
x = 5
In rhombus,diagonals make two congruent triangles
So, ∠ACD = ∠ACB
8) In Rectangle, diagonals are equal and bisect each other
x + 10 = 3x - 18
x - 3x = -18 -10
-2x = -28
x = -28/-2
x = 14
9) a + 36 = 180 { sum of co interior angles is 180}
a = 180 - 36 = 144
a = 144
113 + b = 180 { sum of co interior angles is 180}
b = 180 - 113
b = 67
10) 4th figure

Answer:
Other number is 278.
Step-by-step explanation:
Given that
a + b = 981
One of the numbers = 703
We assume that it is a ; So
a = 703
Other number = b = ?
Put value of a in a + b
a + b = 981
703 + b = 981
b = 278
Answer:
y= 35
Step-by-step explanation:
y directly proportional to x
where x= 2, y= 10
y=kx
10= k× 2
k= 10/2
k= 5
to find y when x is 7
y = kx
y = 5× 7
y= 35
