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 )

Step-by-step explanation:
I did the math
3w + 2 ( 2 - 3w ) + 2
3w + 4 - 6w +2
3w - 6w + 4 + 2
-3w + 6
hope it help
Answer:
x will equal 61 degrees
Step-by-step explanation:
The total degree of a pentagon is 540. You subtract all the angles you have (138, 144, 107, and 90) and that will get your sum.
