Question

3. Find the values of x and y in each of the following figures. b. a. 72°, 69, 105°, 109° b. 144°, 76°, 98°, 42° a. 140 60° 110° 50° 70° 4.​

Answer 1

Answer:

$\huge { \underline\red {\bf{Solution}}}$

Step-by-step explanation:

• The interior angle of angle a =180°-110°=70°
• the interior angle of angle b=180°-120°=60°
• the sum of the angles of a triangle is 180°
• 70°+60°+x°=180°
• 130°+x°=180°
• x°=50°

therefore x =50°.
