Question

the triangle below is isosceles. find the value of y. y = ? (y + 16)° 51°

Explanation:

Step1: Use isosceles - triangle property

In an isosceles triangle, two angles are equal. Here, either \(y + 16=51\) or we use the angle - sum property of a triangle (\(180^{\circ}\)). Let's assume the two given non - vertex angles are equal.
\(y + 16=51\)

Step2: Solve for y

Subtract 16 from both sides of the equation.
\(y=51 - 16\)
\(y = 35\)

Answer:

35
