Answer:
x =72
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
x+77+31 = 180
Combine like terms
x + 108 = 180
Subtract 108 from each side
x+108-108 = 180-108
x =72
Answer:
1/2
Step-by-step explanation:
y=mx+c
so by comparing the two m=1/2
Answer:

Step-by-step explanation:
Given:
An isosceles triangle ABC with AB = AC.
∠A = 
∠B = 
∠C = 
We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.
Therefore, ∠B = ∠C
⇒ 
⇒ 
∴ ∠C =
°
Now, the sum of all the interior angles of a triangle is always 180°.

Therefore, the value of 'y' is 5.
