Question

Find the value of y.
M
51
12y+7
L
Q
51
43
P

Answer 1

y = 3

Explanation:

Forming the equation,

→ 12y + 7 = 43

Now the value of y will be,

→ 12y + 7 = 43

→ 12y = 43 - 7

→ 12y = 36

→ y = 36/12

→ [ y = 3 ]

Hence, the value of y is 3.

Answer 2

• y = 3

Explanation:

Given is a kite because:

• one pair of congruent sides ML and LP,
• second pair of sides also congruent since OQ is perpendicular bisector of angle Q, making MPQ an isosceles triangle, hence MQ = QP.

Since MQ and QP are congruent, set equation and solve for y:

• 12y + 7 = 43
• 12y = 36
• y = 3
