Answer:
144-36=108
Square root 108 = 10.4cm (cb)

Sin(55) =o/h
=10.4/h
xh
H x sin55 =10.4
÷sin55
H= 10.4/sin55
H=12.7cm
CD is 12.7cm to 3 s.f.
Slope (3) y intercept (0,-2)
M∠1 + m∠2 + m∠3 = 360
y + 110 + 90 = 360
y + 200 = 360
- 200 - 200
y = 160
It is the answer because it shows that the first one is 110 degrees and the second one 90 degrees, making a total of 200 degrees; since the angles have a total of 360 degrees, the value of y is 160 degrees.
The answer to A is 25.
The answer to B is 14!
