Answer:

Side b is 15.02,

Angle C is 45.39° and angle A is 71.61°

Step-by-step explanation:

Let in triangle ABC,

BC = a = 16 unit,

AB = c = 12 unit,

∠B = 63°,

By the law of cosine,

b^2=a^2+c^2-2ab cos B

By substituting the values,

b^2 = 16^2+12^2-2\times 16\times 12 \times cos 63^{\circ}=256 + 144 - 384 cos 63^{\circ}=225.67

\implies b\approx 15.02

By the law of sine,

\frac{sin B}{AC}=\frac{sin C}{AB}

\frac{sin 63^{\circ}}{15.02}=\frac{sin C}{12}

\implies sin C= \frac{12sin 63^{\circ}}{15.02}= 0.7119

\implies \angle C\approx 45.39^{\circ}

∵ The sum of all interior angles of a triangle is supplementary,

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A + 63° + 45.39° = 180°

⇒ ∠ A + 108.39° = 180°

⇒ ∠A = 71.61°

nata0808 [166]

Answer:

233.5 in²

Step-by-step explanation:

First we have to find the slant height.

5²+14²=c²

25+196=c²

221=c²

c=14.866

Now we can find the lateral area.

\pirl

\pi(5)(14.866)

=233.51566

To the nearest tenth=
