in an isosceles triangle, the base angles are equal and the vertex angle is 80°. find the measure of the base angles. (note: the angles of a triangle add up to 180°.)

this is multi step equations.

The measure of base angles of isosceles triangle having vertex angle as 80 degree is 50 degree each

Solution:

Given that,  

In an isosceles triangle, the base angles are equal  

Measure of vertex angle =

Need to calculate two equal base angle of triangle  

Lets measure of each of the base angle =

So measured of three angles of triangle are

And as the angles of a triangle add up to 180°  

=> x+ x + 80 = 180

On solving above expression for x we get,  

Measure of base angle = x = 50 degree

Hence measure of base angles of isosceles triangle having vertex angle as 80 degree is 50 degree each

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
