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°

The sales tax in your city is 8.8%, point, 8, percent, and an item costs $63$, before tax.

PIT_PIT [208]

You would pay $5.54 on that item.

Step-by-step explanation:

Given,

Cost of item = $63

Sales tax rate = 8.8%

Amount of sales tax = 8.8% of cost of item

Amount of sales tax = $\frac{8.8}{100}*63$

Amount of sales tax = $\frac{554.4}{100}$

Amount of sales tax = $5.54

You would pay $5.54 on that item.

4x+2x -3+21 28-3=25 14+21=35

6x+18=60 DO=25 OG=35

60-18=42

6x=42

42/6=7

x=7
