Question

find x in the figure ​

Answer 1

Answer:

sum of all angles of triangles is 180°

angle P +angle Q+ angle R=180°

45°+(3x+16)°+68°=180°

113°+16°+x°=180°

x°=180°-129°

x°=51°

Answer 2

Step-by-step explanation:

( 3x + 16)°+68°+45°=180° ( sum of angles of a triangle is 180°)

(3x+16 )°+113°=180°

3x + 16 = 180°-113°

3x= 67°-16°

x = 51/ 3

x = 17 °

(3x + 16 )°=3 * 17+16= 51+16= 67

Q= 67°
