NEED HELP ASAP. Determine the variables, will give Brainliest!!

Answer:
θ = 55° (Approx)
B = 16.5 (Approx)
Step-by-step explanation:
Given:
In Δ first;
H = 7
B = 4
Cos θ = B/H
Cos θ = 4 / 7
Cos θ = 0.57
θ = 55° (Approx)
Given:
In Δ second;
B = x
P = 8
θ = 26°
Tan θ = P / B
Tan 26° = 8 / x
0.4877 = 8 / x
x = 16.5 (Approx)
B = 16.5 (Approx)
