Answer:
CD ≈ 26.0 cm
Step-by-step explanation:
using the sine ratio in right triangle ABD
sin35° = 
= 
= 
( multiply both sides by BD )
BD × sin35° = 12 ( divide both sides by sin35° )
BD = 
≈ 20.92 cm
using the sine rule in Δ BCD
= 
, that is
= 
( cross- multiply )
CD × sin52° = 20.92 × sin102° ( divide both sides by sin52° )
CD = 
≈ 26.0 cm ( to 3 significant figures )
Answer: 24
The area is length times width, or in this case: 6 times 4.
A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b

Answer:
T = m + 500
Step-by-step explanation:
I would assume this question is asking for the sum of the two values. Sorry if this isn't helpful. (T means total btw)
