Answer:
= 130°
Step-by-step explanation:
Angles subtended at the center by the arcs and
are ∠HPG and ∠EPF.
Since these angles are the vertical angles both will be equal.
m∠HPG ≅ m∠EPF
3x - 10 = 2x + 10
3x - 2x = 10 + 10
x = 20
Therefore,
= 50°
Similarly = 50°
In the same way angles subtended at the center will be equal.
m∠EPH ≅ m∠FPG
and
Since °
Therefore, measure of arc EH = 130°
First, we obtain the gradient (slope) of the first parallel line
Recall that since both lines are parallel, we have that,
Thus
Hence, we can find the equation of the parallel line given that it passes through the points (-4, -3)
Using
