21. M List the sides of ABC in order from shortest to
longest

Ummm... I think it would help if you take a screen shot

Step-by-step explanation:

The sum of all angles is 180degrees

100 = 8x +4

X =( 100-4)/8 =12

A = 80

B = 41

C = 59

The largest angle is adjacent to the largest side so

B C A

Step-by-step explanation:

Also can u pls mark me brainliest im new

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

happy to

pls mark as brainliest

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
