For this case, we have that:
- By definition, a rectangle is a parallelogram. So, we discard the first option.
- On the other hand, we have that all rectangles can not be squares, since a square has all its sides equal, while the rectangle, poir definition, no.So, we discard the second option.
- All quadrilaterals are not rectangles because there are other figures with four sides that are not necessarily rectangular. We discard the third option.
- Finally, we have that all squares are rectangles. This statement is true since squares can be rectangles with pairs of equal sides.
Answer:
Option D
To find if a series is either geometric or arithmetic:
it must satisfy this property:
Arithmetic:
a(n+1) - a(n) = const
Geometric:
a(n+1)/a(n) = const
In your case:
r1 = 7 -4 = 3
r2 = 12 - 7 = 5
r1 != r2 (not arirthmetic)
Geometric check:
r1 = 7/4
r2 = 12/7
r1 != r2 (not Geometric)
so neither.
Answer:
Step-by-step explanation:
Answer:
x 100
Step-by-step explanation:
because of the yvz angle its equals 100-12
Answer:
44 degrees
Step-by-step explanation:
x
Let the supplement/compliment by
y
x+
y=90
Complimentary angles add up to 90 degrees.
x+3
y=180
Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:x+y=90 Isolate x:x=90−y Input into the other equation:(90−y)+3y=180Combine like terms, isolate y and its coefficients:2y=90 Isolate yy=45 Input into the first equation:x+45=90 Isolate x:x=45 degrees
