Find the missing angle
PLZ HELP :/

The missing angle are: 123°, 65°

5x+10° = 65°

11x +2° = 123°

Step-by-step explanation:

11x+2° = 5x+10°+58° {the exterior angle formed by producing the side of triangle is equal to two non adjacent angle}

or, 11x - 5x = 58°+10°-2°

or, 6x = 66°

or, x = 66°/6

or, x = 11°

therefore, x = 11°

11x+2° = 11×11°+2°

= 121°+2°

= 123°

5x+10° = 5×11°+10°

= 55°+10°

= 65°

I hope it helped u :)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
