Answer:
B. 16.7
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship between the side adjacent to the angle and the hypotenuse involves the cosine function:
Cos = Adjacent/Hypotenuse
Filling in the numbers from your diagram gives ...
cos(50°) = x/26
Multiplying by 26 gives x.
x = 26·cos(50°)
x ≈ 16.7
Answer:
BZ = 64/23 = 2 18/23
Step-by-step explanation:
The angle bisectors divide the triangle into proportional parts, so we have ...
CB/CY = AB/AY
CB = CY(AB/AY) = 4(8/6) = 16/3 . . . . multiply by CY and evaluate
and ...
BZ/CB = AZ/AC
BZ = AZ(CB/AC) . . . . multiply by CB
But we have ...
AZ = 8 -BZ, so this becomes ...
BZ = (8 -BZ)(16/3)/(10)
BZ(1 +8/15) = 64/15 . . . . add the BZ term on the right to both sides
BZ = (64/15)(15/23) = 64/23 . . . . divide by the coefficient of BZ
BZ = 64/23 = 2 18/23
