Answer:

Step-by-step explanation:
The measure of arc which the right triange cuts from the circle is
this means the central angle has the same measure.
Angle with measure
is inscribed angle subtended on the given arc. Its measure is half the measure of the central angle, hence

Angles with measures
and
are complementary angles (add up to 90°), so

Answer:
The slope is 0.3.
Step-by-step explanation:
1.5x + 4.5y = 18
<u>4.5y</u> = <u>18 - 1.5x</u>
4.5 4.5
y = 4 - 0.3x
First you add like terms in which this case is -.46x and .16x which equals -.3x then divide 6.6 into -.3 which is -22. x = -22
