Answer:
12
Step-by-step explanation:
Its interior angle has measure 150∘. Therefore, the exterior angle has measure 180∘−150∘=30∘. Therefore, the number of sides of the regular polygon with interior angle 150∘ is 12.
Answer:
E) quadrilateral
Step-by-step explanation:
Quadrilateral LMNO has 4 sides, but only two seem to parallel each other and that is why it is only a quadrilateral.
Requirements for each shape:
Square = 4 equal sides, 2 pairs of parallel ones, all right angles
Rectangle = 2 sets of equal and parallel sides, all right angles
Rhombus = 4 equal sides, 2 pairs of parallel ones
Parallelogram = 2 pairs of parallel sides
Quadrilateral = 4 sided polygon with 4 corners
Hope this helps!
Answer:
x=24
Step-by-step explanation:
The opposite angles are equal as per certain theorems.
3x-1=71
3x=72
x=24
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
