7 Max is thinking of a number. His number: is a 6-digit, odd number • has the same number of 1,000s as Is • is greater than half
wel

The two numbers that can possibly be Max's number are 617237 and 627137.

  • We are provided with several characteristics of the numbers about which Max is thinking.
  • The number is a 6-digit number.
  • The number is odd.
  • The numbers have the same digits at 1000 s and 1 s place value.
  • The number is greater than 500,000.
  • The sum of all the digits of the number equals 26.
  • According to the rules, the digits at 1000s and 1s places should be the same as well as odd. They can be 1, 3, 5, 7, or 9.
  • The leftmost digit should be more than 5, so it can be 6, 7, 8, or 9.
  • The remaining digits can be filled in such a way that the total sum is 26.
  • There are a number of possible answers.
  • So, we will take any two such numbers that follow all the rules.

Given: △ABC, m∠C=90° m∠ABC=30°, AL ∠ bisector CL=6 ft. Find: LB
vlada-n [284]

For a better understanding of the solution given here please go through the diagram in the file attached.

To solve this question we will make use of the "Triangle Angle Bisector Theorem", which states that, "An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle."

Thus, in our question, we will have:

\frac{LB}{CL}= \frac{AB}{AC}

The above equation can be rearranged as:

LB=CL\times \frac{AB}{AC}=\frac{CL}{(\frac{AC}{AB})}...(Equation 1)

If we have a proper look at the denominator which is \frac{AC}{AB}, we note that in \Delta ABC, \frac{AC}{AB}=Sin(\angle ABC)=Sin(30^\circ)

Thus, (Equation 1) wil give us:

LB=\frac{CL}{Sin(30^\circ)} =\frac{6}{0.5}=12

<u>Therefore, LB= 12 feet</u>
