14. Trick question, ignore the side.
Call the angle b.
34 + b + b = 180
2b = 146
b = 73
choice b
15. That's intersecting chords so the product of the segment lengths are equal:
5(22)=10 x
x = 5(22)/10 = 11
choice a
16. Intersecting tangent and secant;
Choice a
Answer:
149.14
Step-by-step explanation:
Area of a circle = π
so A = π * 6.89^2 = 149.14 (to 2d.p.)
Answer:
y=-1/2x+1
Step-by-step explanation:
Step-by-step explanation:
3 tan 2x - 4 tan 3x = tan² 3x * tan 2x
3 (tan 2x - tan 3x) = tan 3x + tan² 3x * tan 2x
= tan 3x (1 + tan 3x * tan 2x)
3 (tan 2x - tan 3x)/(1 + tan 3x * tan 2x) = tan 3x
3 * (- tan x) = tan 3x
-3tanx = (3 tan x - tan³ x) / (1 - 3 tan² x)
3 - tan² x = - 3 + 9 tan² x
tan x = + √3 /√5 or - √3/√5
