1) Solve for Side A.<br><br> 2) Solve for Angle B.
avanturin [10]

Answer:

solution given;

let

AB=a

AC=b=30ft

AB=c=20ft

<A=115°

By using Cosine rule.

a²=b²+c²-2bc cos angle

a²=30²+20²-2*30*20 Cos 115°

a²=1807.1419

a=√[1807.1419]

a=42.51

Side A is 42.51ft.

Again

Cos B=\frac{a²+c²-b²}{2ac}

Cos B=\frac{42.51²+20²-30²}{2*42.51*20}

Cos B=0.7687

<B=Cos -¹(0.7687)

<B=39.46°

Angle B is 39.46

LiRa [457]

Answer: 8\sqrt{5}

Step-by-step explanation:

By the geometric mean theorem,

\frac{y}{16}=\frac{4}{y}\\\\y^{2}=64\\\\y=8

So, by the Pythagorean theorem,

8^2 + 16^2 = x^2\\\\320=x^2\\\\x=\boxed{8\sqrt{5}}
