The length is 46.10 cm.
Since ∠BCA = 50.5°, ∠ACD = 180-50.5 =129.5°. This means that ∠CAD = 180-(129.5+35.8) = 14.7°. We can now use the law of sines;
sin 14.7/20 = sin 35.8/x
Cross multiply:
x*sin 14.7 = 20*sin 35.8
Divide both sides by sin 14.7:
x = (20*sin 35.8)/(sin 14.7) = 46.10
Answer:
Step-by-step explanation:
y - 72 = 8(y - 3)
Distribute the 8 into (y - 3).
y - 72 = 8y - 24
Subtract 8y from both sides.
-7y - 72 = -24
Add 72 to both sides.
-7y = 48
Divide both sides by -7.
y = -48/7 or approxametly -6.9.
Proof:
y - 72 = 8(y - 3)
Substitute variable.
-48/7 - 72 = 8(-48/7 - 3)
Subtract.
-552/7 = 8(-69/7)
Multiply 8 by the inside term -69/7.
-552/7 = -552/7.
