Analyzing Ratios of Similar Right Triangles
Try it
A
= 30°
m2 C = 60°
Create similar right triangles by changing the scale factorm
of the right triangle
When the scale factor is 1, what is the ratio of the side
length of the side opposite ZA and the length of the
hypotenuse?
Change the scale factor to 3. What is the ratio of the side
length of the side opposite ZA to the length of the
hypotenuse?
What is the ratio of the side length of the side opposite
any 30° angle and the length of the
hypotenuse?
Scale factor: n = 1

1/2

1/2

1/2

Step-by-step explanation:

1/2 for each box

Step-by-step explanation:

sorry, can't i suggest going to algebra.com

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
