Ashley can help his father and it is a very easy that she can solve for the triangular portion of the roof by using the formula of the area of a triangle which is equivalent to A=1/2*H*B. Ashley needs to measure the length of both base and height of the triangular portion of the roof. Then, she can proceed with the equation.
Answer:
<u>A = 61°</u>
<u>B = 72°</u>
<u>C = 47°</u>
Step-by-step explanation:
Well, first of all, we can see that:
So, we can find angle B.
Now, we can see to that angle C is just 47°
Finally, we know that the sum of all angles in a triangle is 180°, so we have:

"3 less than twice 'x' " . . . . that's (2x - 3)
" 2 more than the quantity (3 x) " . . . . . that's (3x + 2)
Their product is
(2x - 3) (3x + 2) .
If you want to expand it to a single expression, perform the multiplication,
and you have
6x² - 5x - 6 .
The point B is located at (-6.5, 0)
<h3>How to determine where is point B located?</h3>
The points are given as:
A = (1/2, 6)
Center = (-3, 3)
The center is calculated as:
Center = 0.5 * (x1 + x2, y1 + y2)
So, we have:
(-3, 3) = 0.5 * (1/2 + x, 6 + y)
This gives
(-6, 6) = (1/2 + x, 6 + y)
Solve for x and y
1/2 + x = -6
6 + y = 6
This gives
x = -6.5
y = 0
Hence, the point B is located at (-6.5, 0)
