How do you get the answer or what is the answer? I’m confused and the teacher is unavailable. The problem is asking to find the measure of arc ABC. Will give out brainliest

60 degrees

Step-by-step explanation:

A trapezoid has a total of 360 degrees and you know m D is 118 so m C will be 118. Added together is 236. subtract that from 360 you get 124 then divided by 2 is 60.

118x2=236     360-236=124     124/2=60

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

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
