∠ B = 116°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , that is
∠ B + 28° + 36° = 180°
∠ B + 64° = 180° ( subtract 64° from both sides )
∠ B = 116°
116°
Step-by-step explanation:
The sum of interior angles of a triangle is 180°
so
180 - 36 - 28 =
116°
A vertex is a corner
notice, #vertices=#sides
we cannot use a circle since it is 1 side but 0 vertices
square,trapezoid, triangle, pentagon, hexagon, octogon
square+triangle is 4+3=7
next is trapezoid which is 4 sides
the shapes can be
trapezoid, square, triangle or
trapezoid, rhombus, triangle or
trapezoid, rectangle, triangle or
rectangle, rhombus, triangle (there are more)
