Answer:
89.0°
Step-by-step explanation:
The segment from the centre of the circle to the chord is a perpendicular bisector, hence
third side of right triangle = 12.7 ÷ 2 = 6.35
The angle subtended at the centre by arc CD is twice the angle subtended by the right triangle at the centre
The triangle from the centre to C is congruent to the triangle from the centre to D
Calculate the angle (Θ ) in the right triangle using the sine ratio
sinΘ = 
= 
Θ = 
( ) ≈ 44.5°
Hence
measure of CD = 2 × Θ = 2 × 44.5 = 89.0°
The so-called pythagorean triple will just be the distance between both points,
Well they each have 3 solutions
The solutions to 7x-7y=-6 are:
- Slope=1
- X-intercept= - 6/7=-0.85714
- Y-intercept= 6/7= 0.85714
The answers to 13x-9y=16 are:
- Slope=2.889/2.000=1.444
- X-intercept=16/13=1.23077
- Y-intercept=16/-9=1.77778

112 = 4.5p +40
112-40 =4.5p
72= 4.5p
72/4.5 = p
p= 16

Answer:
$24
Step-by-step explanation:
calculate 20% of $30 and subtract the discount from the cost price
20% = 
= 0.2, hence
discount = 0.2 × $30 = $6
buying price = $30 - $6 = $24
