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 coordinate of point M = (-6,7)
Explanation:
The Median of a triangle is a line segment from a vertex to the midpoint of the opposite side of a triangle.
Given: has vertices T(3,6) , R(-3,10) and E(-9,4).
Here, line TM is a median of triangle TRE where M is the midpoint of RE.
The midpoint of M of the line segment from R(-3,10) to E(-9,4) is;
M =
Therefore, the coordinate of point M is, (-6,7).
Answer:
Step-by-step explanation:
we know that
In the right triangle DEF
----> by TOA (opposite side divided by adjacent side)
