In triangle abc, angle a is congruent to angle b and
themeasure of angle a is 54. find the measure of angle c, the value
ofac and bc.

Angle C=72º

Step-by-step explanation:

If two angles are congruent they are equals then angle A is 54º and angle B is 54º and the sum of the internal angles of a triangle is 180º then.

C=180º-54º-54º=72º

To know the value of on AC and BC we have to know the value of the other side AB, to find the values of the sides we can use the law of sines;

the y will be in still but your answer will be y x 3

step-by-step explanation:

jk: )

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
