Hey!
So the first thing we can notice is that we are given the equation of the line parallel to the one we need to find. Two parallel lines always have the same slope. We can tell by looking at the equation that the slope of the line that we have been given is 1 and since the lines are parallel the slope of the line we need to find is also 1.
Knowing this and a point that the line passes through, we can find the y-intercept or b:
y = mx + b
4 = 1(1) + b
4 = 1 + b
3 = b
Since we know that the y-intercept is 3, we can plug this back into the slope intercept form equation along with the slope to get our equation:
y = x + 3
There is only one triangle possible having angle 50, 50, 80.

What is isosceles triangle?</h3>
An Isosceles Triangle has the following properties:
- Two sides are congruent to each other.
- The third side of an isosceles triangle which is unequal to the other two sides is called the base of the isosceles triangle.
- The two angles opposite to the equal sides are congruent to each other.
It is given that, 2 angles of a triangle as:
∠1 = 50°
∠2 = 80°
Now we know the Angle sum property of a triangle that sum all three interior angle in a triangle is
.
i.e., ∠1+∠2+∠3=
.
So, 50° +80°+ ∠3 = 
∠3 = 50°
As two angles of the triangle are equal that means it is a isosceles triangle.
There is no possibility of getting a right angles triangle.
Hence, there is only one triangle possible with these measurements .
