we know that
<u>Vertical angles</u> are a pair of opposite and congruent angles formed by intersecting lines.
so
Let
x1---------> angle vertical 1
x2---------> angle vertical 2
x1=x2 ------> equation 1
in this problem
if the vertical angles formed are supplementary
that means that
x1+x2=180 ------> equation 2
substitute equation 1 in equation 2
x1+x1=180
2x1=180
x1=180/2
x1=90 degrees
therefore
<u>the answer is</u>
The vertical angles are right angles
Answer:
y-intercept is the value of y when x is equal to zero. Because the y intercept is a point on a graph, you'll usually write it in point/ coordinate form.
Step-by-step explanation:
The y-intercept is where the parabola of a function crosses (or intercepts) the y axis.
Answer:
See below
Step-by-step explanation:
Three lengths will be a triangle only if the sum of two sides is greater than the third side.

This is a triangle.

This is not a triangle.

This is not a triangle.

This is a triangle.
Answer:
x ≈ 61.3
Step-by-step explanation:
Using the Sine rule, that is
=
( cross- multiply )
5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )
sin x =
≈ 0.87729, thus
x =
(0.87729) ≈ 61.3
