Answer:

w = 6.7451

x = 8.0805

Step-by-step explanation:

Find W

Tan(56) = opposite / adjacent

opposite = 10

Adjacent = w

Tan (56) = 10/w

w*Tan(56) = 10

w = 10 / tan(56)

w = 10/ 1.4826

w = 6.7451

Find x

Tan (34) = 10 / (w + x)

Tan (34) = 0.6745

(w + x) * Tan(34) = 10

w + x = 10 / tan(34)

w+ x = 10 / 0.6745

w + x = 14.826

But we found w = 6.7451

6.7451 + x = 14.826

x = 14l826 - 6.7451

x = 8.0805
