What is the length of side bc of the triangle? enter your answer in the box. units what is the value of x? enter your answer in the box. x= what is the value of x? enter your answer in the box. x =

Ques 1)

We are given:

m∠B=m∠C

As we know that sides opposite to equal angles are equal.

Hence,

Length of AC=Length of AB.

i.e. x+8=2x-1

i.e. 2x-x=8+1

i.e. x=9

Also, the length of side BC is:

3x-3=3×9-3

      = 27-3

      = 24 units.

The value of x is: 9

Length of BC is: 24 units.

Ques 2)

As we could see that all the three angles of a triangle are equal.

Hence,

The sides opposite to equal angle are equal.

i.e.

6x-3=3x+6

i.e.  6x-3x=6+3

i.e. 3x=9

i.e. x=3

Now the length of side of BC is: 5x=5×3=15 units.

Hence,

Value of x=3

Length of BC=15 units.

Ques 3)

All the three sides of a triangle are equal.

That means:

all the three angles of a triangle are also equal.

Hence, all the angles be (7x+4)°

As we know that the sum of all the three angles of a triangle is 180 degree.

Hence,

Hence, the value of x=8

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
