1.an exterior angle at the vertex of an isosceles triangle
measures 150°. find the measure, in degrees, of a base
angle of the triangle.

2.vertex angle a of isosceles triangle abc measures 70°.
what is the measure, in degrees, of an exterior angle at b?

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is
