Please help<br><br> Boats A, B, C, and D are all the same distance from Boat O.
BlackZzzverrR [31]

Answer:

α = 62°

β = 56°

gamma = 90°

Step-by-step explanation:

ΔAOB is isosceles, so m∠A = m∠ABO = 28

28 + 28 + m∠AOB = 180

m∠AOB = 180 - 28 - 28 = 124

β = 180 - 124 = 56

arcAB = 124

ΔBOC is isosceles.  α = m∠BCO = 1/2(arc AB) = 1/2(124) = 62

∠D is inscribed in a semicircle

m∠D = gamma = 90°

Tickets marked up 35% to 59.40 what is original price
Art [367]
So percent means parts ouf of 100
x%=x/100

so marked up form original to new price
100%=original
marku=35%
new price=100+35=135%
new price=59.40
so therefor

59.40=135/100 of original price
'of' means mutiply
replace 'origional price' with x
59.40=135/100 times x
simplify 135/100 to 27/20
59.40=27/20 times x
mutiply both sides by 20/27 to clear fraction
1188/27=x
44=x

original price=$44
