Answer:
Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that 
is an isosceles triangle. With this information, we can draw an isosceles triangle to find 
. Since the base angles of an isosceles triangle are equal, we can solve for :
(Angle sum of triangle is 
)
(Base angles of isosceles triangles are equal, there is an image attached to show that is one of the base angles)
Hope this helps :)

Answer:
B
Step-by-step explanation:
Here, we are told that the rectangle is enlarged by a factor of 6, we now want to calculate the new area of the said rectangle.
Now, for the rectangle to have an area of 20, mathematically the area of a triangle can be calculated using the formula L * B
where L is the length and B is the breadth
our product here is 20, so any product that gives 20 would be a good fit as the value of the width and length of the rectangle
So, let’s say the sides measure 5 inches by 4 inches
Enlarging these by a factor of 6, we have 30 inches by 24 inches
The new area of the rectangle would thus be ;
30 inches * 24 inches = 720 inches^2
