Please answer please both please

see explanation

Step-by-step explanation:

(5)

Using the tangent ratio in the right triangle

tan ? = = , thus

? = ( ) ≈ 30° ( to the nearest degree )

(6)

Use any of the 3 trig ratios to solve.

Using the cosine ratio

cos ? = = , thus

? = ( ) ≈ 13° ( to the nearest degree )

yep

step-by-step explanation:

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
