see explanation
Step-by-step explanation:
To verify cos²A + sin²A = 1 with A = 90° , then
cos²90° + sin²90°
= (0)² + (1)²
= 0 + 1
= 1
Answer:
204
Step-by-step explanation:
3.4[6(4)+6^2]=
3.4[24+36]=
3.4[60]=
204
Hope this helps!
First multiply, so 42 x 39, which equals 1,638, then estimate, round 42 to 40, and 39 to 40, and do 40 x 40 = 1,600 which is close to your answer, so good.
Answer:
Step-by-step explanation:
Given are the vertices of a quadrilateral.
WE have to find the name of the quadrilateral
WE have slope of AC = (5-1)/(7-3) = 1
and slope of BD = (2-5)/(7-4) = -1
Since m1m2 =-1 we get
the diagonals cut at right angles
This property is special property for square, rhombus and kite only.
Let us check if diagonals bisect each other
Mid point of AC = 
Mid point of BD =
Since diagonals do not bisect this is neither rhombus nor square.
Only possibility is kite
Just divide 402 by 8
402 is in the house 8 is on the outside
