The measures of the angles of the isosceles triangle are 55, 55 and 70.
Explanation:
An isosceles triangle has two congruent base angles and a vertex angle.
Let
b
=the measure of one of the base angles.
Let
v
=
the measure of the the vertex angle.
The vertex angle is 40 degrees less than the sum of the base angles.

Answer:
x < 4
So the dot on the graph would be an open dot and the number line would be shaded to the left.
Step-by-step explanation:
I do not see a number line, but
x < 4
So the dot on the graph would be an open dot and the number line would be shaded to the left.
Answer:
$28.12
Step-by-step explanation:
$9.19 x 40 = $367.60 x 7.65% = $28.12
Unlike terms displays terms which are not the same. x+2y would be the answer.
