Mathematics
1 answer:
anyanavicka [17]3 years ago
5 0

Answer:

area of shaded portion = 226.09 m²

Step-by-step explanation:

area of circle = πr² = (3.14)(18.6²) = 1086.314 m²

area of 123° segment = (123/360)(1086.314) = 371.157 m²

cos 61.5° = height/18.6 = 8.875

height of triangle = 8.875 m

sin 61.5° = 1/2base/18.6 = 16.346,   base = 32.692 m

base of triangle = 32.692 m

area of triangle = 1/2bh = 1/2(8.875)(32.692) = 145.071 m²

area of shaded portion = 371.157 - 145.071 = 226.09 m²

5 1/3 x+8 1/2 =3 1/3 please answer need answers ASAP
SVETLANKA909090 [29]

Answer:

5 1/3 x+8 1/2 =3 1/3 ?

the correct answer is -1.774

Step-by-step explanation:

51/3x + 81/2=31/3 In order to find x, we follow BODMAS rule

so we have,[ 51/3] x + 81/2 =31/3

we have   51x/3 + 81/2=31/3

we collect the like terms;

51x/3= 31/3- 81/2

finding the lcm

51x/3= 2[31} - 3{81}/6

51x/3= 62-243/6

51x/3= -181\6

by using cross multiplication

we have;

6{51x}= 3{-181}

306x = -543

divide both sides by 306

we have;

x = - 1.774

check your answer from

306x=-543

306{-1.774}= -543

-543= -543
