What is the value of y, in a triangle that is equilateral with the top being 54 degrees and the two angles at the bottom being Y degrees, what is the answer im baffled?
Answer Options;
A.)63 degrees
B.)126 degrees
C.)72 degrees
D.)54 degrees

A:63°

Step-by-step explanation:

THE SUM OF ANGLES IN A TRIANGLE IS 180°

180°-54°=126°

126°÷2=63°

THE ANSWER IS A:63°

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
