Answer:
Option A
10.5 m²
Step-by-step explanation:
The area of a triangle is half the product of its base by its height.
Where b is the base and h is the height.
In this triangle b = 6.1 m.
The height of this triangle is a line perpendicular to its base that goes to the vertex opposite the base.
We do not know this length. But this line h divides the triangle into two rectangular triangles.
So for these two triangles the angle that is opposite to the height h is: 47 °
Therefore we know that senx is defined as:
Where:
Opposite side = h
hypotenuse = 4.7 m
x = 47
Finally, the area is:
Answer:
58 and 60
Step-by-step explanation:
well if we say that x is the first integer
then we have that the next one is
x+2
so we have
and the other one is
