Answer:

Step-by-step explanation:
Notice that angles <1 and <3 are opposed by the vertex, which makes them of equal measure, therefore, <1 = 47 degrees.
Notice as well that angles <1 and <2 combine into a straight line, therefore, they are supplementary angles whose addition gives 180 degrees then we can find the value of angle <2 via:

And finally, angle <4 is opposite through the vertex to angle <2, and therefore they must have the same measure. So, <4 = 133 degrees.
Answer:
x = -8
Step-by-step explanation:
y = 3x/4
Substitute the value of -6 into y.
-6 = 3x/4
Multiply both sides by 4.
-24 = 3x
Divide both sides by 3.
x = -8.

Answer: 1.9
Step-by-step explanation:
You want to multiply 9x10 which is 90.
Then you want to add 44+pi
now pi can be shown as 3.14 or 22 over 7
in this case you want to add 44 + 3.14 which gives you 47.14
now you want to divide 90/47.14 which gives you 1.90920661858 or in short
1.9
Answer:
<h2>C.</h2>
Step-by-step explanation:
The equationof a circle:

<em>(h, k)</em><em> - center</em>
<em>r</em><em> - radius</em>
<em />
We have <em>center = (4, -1) → h = 4, k = -1</em>, and <em>r = 9</em>.
Substitute:
