Question

Stuck on this problem can ya'll help plz

Answer 1

y=1

Explanation:

The interior angles of a triangle always add up 180°, so we can work backwards to find the value of y.

We already know the value of the first 2 angles. So, let's create an equation.

77+68+35y=180

We can simplify to make the equation easier to solve.

77+68+35y=180

145+35y=180

Now, we can start solving the equation. Since 145 is being added, we can subtract 145 from both sides.

145+35y=180

-145 -145

35y=35

Now, we can divide both sides by 35 to find the answer.

35y=35

35y÷35=35÷35

y=1

So, the value of y is 1°.

Hope this helped!
