Answer:
Step-by-step explanation:
z = 180 - (180 - 114.8) - 45.6 = 114.8-45.6 = 69.2°
Answer:
Slope = -b/a.
Step-by-step explanation:
Note that the relation between 2/3 and -3/2 is that their product is -1.
If the slope is a/b then we have a/b * m = -1 where m is the slope of the perpendicular line .
So m = -1 / a/b
= -b/a.
The produce = a/b * -b/a = -1.
Answer:
; see graph.
Step-by-step explanation:
Using the slope formula:

Answer:
Choice A
Step-by-step explanation:
Answer:
88
Step-by-step explanation:
Sum of angles in a quadrilateral= 360 degrees
<OCA=90degrees [ tangent perpendicular to the circle.
<OBA= 90degrees =tangent perpendicular
to the circle
<OCA + <OBA +92 + <OAB= 360
90 + 90 + 92 + <OAB = 360
272 + < OAB = 360
<0AB= 360- 272 =88 degrees
