Step-by-step explanation:

Given

mZEFH = (5x + 1)'

mZHFG = 62°

mZEFG = (18x + 11)',

The addition property of the angle is true

mZEFG = mZEFH + mZHFG

(18x + 11) = (5x + 1)'+  62

18x+11 = 5x + 63

collect like terms

18x - 5x = 63-11

13x = 52

divide both sides by 13

13x/13 = 52/13

x = 4

Since angle mZEFH = (5x + 1)' and x = 4, we will substitute x = 4 into the function;

mZEFH = 5(4) + 1

mZEFH = 20 + 1

mZEFH = 21°

Similarly for mZEFG = (18x + 11)'

mZEFG = 18(4) + 11

mZEFG =72+11

mZEFG = 83°

Answer:

  • - 55

Step-by-step explanation:

  • 20 - 15(2²· 5/4) =      Exponent
  • 20 - 15(4 · 5/4) =       Parenthesis
  • 20 - 15(5) =               Multiplication
  • 20 - 75 =                   Subtraction
  • - 55

Solve to find x <br> log (3x+5) to base 5= 2log (1-3x) to base 25
Eduardwww [97]

Answer:

x = -2/ 3

Step-by-step explanation:

in order to cancel out the logs they should have common bases

\mathsf{ log_{5}(3x + 5) = 2 log_{25}(1 - 3x)  }

we can write 25 as 5²

\mathsf{ \implies  log_{5}(3x + 5) =  2 \: log_{ {5}^{2} }(1 - 3x)  }

we know that the reciprocal of the exponents of the bases are multiplied to the log

\mathsf{ \implies  log_{5}(3x + 5) =   \frac{1}{\cancel{2} } \times \cancel{2} \: log_{ 5}(1 - 3x)  }

and now since the logs have common bases

\mathsf{ \implies  \cancel { log_{5}}(3x + 5) = \cancel{ log_{ 5}}(1 - 3x)  }

we're left with

\mathsf{ \implies 3x + 5 = 1 - 3x}

\mathsf{ \implies 9x = -4}

<u>x = -2/ 3</u>
