Answer:
5) 162
6) 61.6
Step-by-step explanation:
Area of triangle =
Area of rectangle = w * l
5)
Left triangle Area =
= 2*3
=6
Right triangle Area =
=
=28
Rectangle Area = 16*8 = 128
Total Area = 128+28+6 = 162
6)
12-10 = 2
base of each traingle is 2/2 = 1
Left triangle = right triangle = = 2.8
Rectangle = 10*5.6 = 56
Total = 2.8+2.8+56 = 61.6
Answer:
The augmented matrix for the system of equations is .
Step-by-step explanation:
This system consists in three equations with three variables (,
,
).The augmented matrix of a system of equations is formed by the coefficients and constants of the system of linear equations. In this case, we conclude that the system of equations has the following matrix:
The augmented matrix for the system of equations is .
In the parallelogram ABCD, join BD.
Consider the triangle Δ ABD.
It is given that AB > AD.
Since, in a triangle, angle opposite to longer side is larger, we have,
∠ ADB > ∠ ABD. --- (1)
Also, AB || DC and BD is a transversal.
Therefore,
∠ ABD = ∠ BDC
Substitute in (1), we get,
∠ ADB > ∠ BDC.
