The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle?
skad [1K]
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

the volume of a cylinder is 1,692.46 in cubed. if the radius becomes three times as large, what will be the cylinder's volume?
ivanzaharov [21]
We know that
original volume of a cylinder=pi*r²*h
volume=1692.46 in³
1692.46=pi*r²*h

<span>if the radius becomes three times as large
so
r=3*r
new volume=pi*(3*r)</span>²*h----> 9*pi*r²*h
new volume=9*original volume
new volume=9*1692.46----> 15232.14 in³

the answer is
the new volume is 15232.14 in³

What is <br> x+3y=15<br> 3x+2y=10<br> URGENT
gregori [183]

Simplifying

2x + 3y = 1

Solving

2x + 3y = 1

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

2x + 3y + -3y = 1 + -3y

Combine like terms: 3y + -3y = 0

2x + 0 = 1 + -3y

2x = 1 + -3y

Divide each side by '2'.

x = 0.5 + -1.5y

Simplifying

x = 0.5 + -1.5y
