Answer:
Step-by-step explanation:
Lets start by labeling the triangle. Lets say the height is x and the base is x-16.
Next, we know the area of the triangle is 96, so we should make an equation. The area (96) of a triangle is (b*h)/2. So lets substitute.
96=[(x-16)*x]/2
Now, we should simplify the equation. Let us start by moving the /2 to the other side and making it *2.
192=(x-16)*x
Open parenthesis and get
192=x^2-16x
simplify and get
x=24
x is the height so the base must be x-16.
base=8, height=24
3,5,7,9 i think thos is right

Answer:
Step-by-step explanation:
1.
The supplementary angles to ∠x are adding to 180° and are ∠HGC and ∠BGA
2.
If ∠DGE = 90° , then
∠CGD is also 90° because ∠DGE and ∠CGD are a linear pair and
∠HGC is also 90° because ∠DGE and ∠HGC are vertical angles
