Answer:
17degrees
Step-by-step explanation:
Since the triangle ABC is a right angled triangle, one of the angle is 90 degrees
The sum of angle in a triangle is 180
m<A + m<B + m<C = 180
73 + 90 +m<C = 180
163 +m<C = 180
m<C = 180-163
m<C = 17 degrees
Hence the third angle is 17degrees
Answer:
Prob.3
Denote r: radius of circle O
Formula for calculating AOB sector:
Area = pi*r^2*angle/360
Area = pi*r^2*45/360 = 18 pi
=> r^2 = 18*360/45 = 144
=> r = 12
For prob.4, give it a try, follow the formula I gave. Good luck !
(answer : r = 6)
The correct answer would be (0,2) since in standard form the y-int is C/B
C=-4 & B=-2
C/B = -4/-2 4/2 = 2/1 = 2
y-intercept = 2
Answer:
4
Step-by-step explanation:
Plug in the standard deviation formula. This is new to me but it took some research.. Hope it helps
