Find the missing side lengths

Mathematics
1 answer:
Mashcka [7]3 years ago
7 0

Answer:

y = 9√3

x = 18

Step-by-step explanation:

taking 30 as reference angle

b = y

p = 9

h = x

so

tan30 = p/b

1/√3 = 9/b

or, b = 9√3

so

h^2 = p^2 + b^2\\x^2 = 9^2 + y^2\\or, x^2 = 81 + (9\sqrt{3} )^2\\or, x^2 = 81 + 243\\or, x ^2 = 324\\or, x =\sqrt{324} \\\\so x = 18

3/x+2 = 2/x−1 pleasee help
olga_2 [115]
So you have:
\frac{3}{x} + 2  =  \frac{2}{x} - 1&#10;

1) Start off by multiplying both sides by x to simplify the problem:
\frac{3}{x} + 2 = \frac{2}{x} - 1 \\&#10;x(\frac{3}{x} + 2) = (\frac{2}{x} - 1)x\\&#10;3 + 2x = 2 - x&#10;

2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
3 + 2x = 2 - x\\&#10;3x = -1

3) Finally, divide by 3 on both sides to find the value of x:
3x = -1\\&#10;x =  \frac{-1}{3}

------

Answer: x = \frac{-1}{3}

UkoKoshka [18]

Answer:

15

Step-by-step explanation:

Population size= 2107+903+1505+1499

                        = 6014

Calculating the sample of ward B by using the stratified random sampling formula:

Stratified Random Sample, np= ( Np / N ) * n

where

np= pth stratum  sample size

Np= pth stratum  population size

N = population  size

n = sample size

Stratified Sample (ward B) = 100 / 6014 * 903 = 15 !
