To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Answer:
Lol, no clue if this will help or not, but hopefully it does.
Answer:
x = -3
Step-by-step explanation:
<h3>Axis of symmetry: </h3>
Axis of symmetry is the vertical line that divides the parabola into two equal halves and it passes through the vertex of the parabola.
From the graph, Vertex (-3, 4)
Axis of symmetry: x = -3
Answer:
s = 11
Step-by-step explanation:
Given
=
( cross- multiply )
8(s - 2) = 72 ( divide both sides by 8 )
s - 2 = 9 ( add 2 to both sides )
s = 11
Answer:
see the explanation
Step-by-step explanation:
we know that
The equation of a horizontal line is equal to the y-coordinate of the point that passes through it
In this problem we have

This is a horizontal line (parallel to the x-axis)
The slope of this line is equal to zero
so
All points that pass through the line will have the same y-coordinate equal to -5
see the attached figure to better understand the problem
