Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents. ​
Brilliant_brown [7]

9514 1404 393

Answer:

  1. 85°
  2. 60°

Step-by-step explanation:

1. Angle JKL is half the measure of the intercepted arc JK.

  (1/2)JK = 1/2(360° -190°) = (1/2)(170°) = 85°

  angle JKL is 85°

__

2. The angle between tangents is the supplement of the intercepted arc.

  angle JKL = 180° -(360° -240°)

  angle JKL = 60°

The function has an intercept of -2 and y intercept of -2/3. Write an equation.
poizon [28]

Answer:

y= -1/3x - 2/3

Step-by-step explanation:

y- intercept is (0, -2/3) and the x intercept is (0, -2).

To find the slope of an equation, you do rise over run. To get from (0, -2/3) to (0, -2), you rise 2/3 and run -2. 2/3 divided by -2 is -1/3, that is where you get the slope from.

If a=5+2i, b=-3+i and c=4i(2+3I), determine ab+c in simplest a+bi form
Nady [450]

Answer:

-29+7i

Step-by-step explanation:

(5+2i)(-3+i)

-15+5i-6i+2i²

i²=-1

Simplify

-17-i

Add c

c=4i(2+3i)

=8i+12i²

=8i-12

-17-i+8i-12

-29+7i
