Soloha48 [4]

Answer:

A = 137° a = 14 cm

B = 26° b = 9 cm

C = 17° c = 6 cm

Step-by-step explanation:

<u>Cosine rule</u>

$c^2=a^2+b^2-2ab\cos (C)$

$\implies C=\cos^{-1}\left(\dfrac{c^2-a^2-b^2}{-2ab}\right)$

where:

c is the side opposite angle C

a and b are the sides with C as the included angle.

Given:

a = 14 cm
b = 9 cm
c = 6 cm

$\implies C=\cos^{-1}\left(\dfrac{6^2-14^2-9^2}{-2(14)(9)}\right)$

$\implies C=\cos^{-1}\left(\dfrac{241}{252}\right)$

$\implies C=16.99128694..\textdegree$

$\sf \dfrac{sinA}{a}=\dfrac{sinB}{b}=\dfrac{sinC}{c}$

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

$\sf \implies \dfrac{sinB}{9}=\dfrac{sin(16.991..)}{6}$

$\sf \implies B=sin^{-1}\left(\dfrac{9sin(16.991..)}{6}\right)=25.99797699...\textdegree$

Sum of interior angles of a triangle = 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ ∠A = 180° - 25.997...° - 16.9912...°

⇒ ∠A = 137.0107361...°
