Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
Answer from: Quest
< coa = 150 ( given)
as ba and bc are tangents
so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre
so in quadrilateral oabc
< coa + < oab + < ocb + < abc = 360
150 +90+90 + < abc = 360
330 + < abc = 360
< abc = 360 -330 = 30
so < abc = 30

Answer from: Quest
the smallest possible measurement of the width is 14 feet
step-by-step explanation:
let's assume length of parallelogram is 'l'
width of parallelogram is 'w'
the perimeter of a parallelogram must be no less than 40 feet
so, we get
we are given
length of parallelogram is 6 feet
so,
l=6
we can plug it
now, we can solve for w
subtract both sides by 12
divide both sides by 2
and we get
so,
the smallest possible measurement of the width is 14 feet
