Step-by-step explanation:
m∠3+ m∠5 = 180° (co-int angles are supplementary)
5x+ 10 + 3x + 10 = 180° (co-int ∠'s, parallel lines)
8x + 20 = 180
8x = 160
x= 160/8
x= 20°
Answer:
x = 59°
y = 130°
Step-by-step explanation:
Find x:
Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem
Therefore,
x = ½(118°)
x = 59°
Find y:
y = 2(180 - (56 + x)) => inscribed angles theorem
Plug in the value of x
y = 2(180 - (56 + 59))
y = 2(180 - 115)
y = 2(65)
y = 130°
Answer:
<em>(1,0) and (3,0)</em>
Step-by-step explanation:
The roots are always shown where the parabola crosses the x-axis.
In this particular graph, the parabola crosses at (1, 0) and (3, 0). Which means the roots are:
<em>x = 1 and x = 3</em>
f(x) means x = -2 if you multiply 1/2 by -2 you get -1
