2x + 3x + 10° = 180°
5x + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 170 ÷ 5
x = 34
The largest angel :
3x + 10° = 3(34) + 10° = 102 + 10° = <u>1</u><u>1</u><u>2</u><u>°</u>
So, the answer is 112°

Answer:
R = 4 cm
Step-by-step explanation:
A = pi * r^2
51 = 3.14 r^2
r^2 = 51/3.14
r^2 = 16
r = 4 cm
*Note:- neglect the diameter of the the larger circle
x=-60
