In all triangles, inner angles add to 180 degrees.
In an isosceles triangle, the base angles are the same and the vertex angle is different from the rest.

b= (180-40)/2
b= 140/2
b=70

Final answer: 70 degrees

Solve the system of equations using substitution. Show your work<br> y=2x + 3<br> y=3x + 1
FrozenT [24]

Answer:

x=2 and y=7

Step-by-step explanation:

Step: Solvey=2x+3for y:

y=2x+3

Step: Substitute2x+3foryiny=3x+1:

y=3x+1

2x+3=3x+1

2x+3+−3x=3x+1+−3x(Add -3x to both sides)

−x+3=1

−x+3+−3=1+−3(Add -3 to both sides)

−x=−2

−x

−1

=

−2

−1

(Divide both sides by -1)

x=2

Step: Substitute2forxiny=2x+3:

y=2x+3

y=(2)(2)+3

y=7(Simplify both sides of the equation)

In his Fourth of July speech, Douglass says that "above your national, tumultuous joy, I hear the wail of millions.” To what is
krok68 [10]
I think that what Frederick Douglass meant by the "wail of millions" is that while the 4th of July is a great day to be celebrated by non-African American people as it meant the true independence of the 13 colonies from Great Britain and freedom for many of its citizens, in fact slavery is still intact at the time of his speech in 1852 and so July 4th cannot be celebrated by the vast majority of the black people in the US who are still under the terrible yoke of slavery.
