Answer:
x = 36.5
Step-by-step explanation:
The two triangles are similar so we can use the similarity ratio to find x
AB ~ DE and BD ~ BA
15/31 = x/(x+39) cross multiply expressions
31x = 15x + 585
31x - 15x = 585
16x = 585 divide both sides by 16
x = 36.5 approximately
Answer:Temperature of 10 degrees
Step-by-step explanation:
The others involve a decrease of 10 units, justifying use of a megative number.
Answer: Option B. 96 ft^3
Solution:
Volume of the prism: V=?
V= A * H
Height of the prism: H=4 ft
Area of the base (triangle) : A=b*h/2
Base of the triangle: b=6 ft
Height of the triangle: h=8 ft
A=(6 ft)*(8 ft)/2
A=48 ft^2/2
A=24 ft^2
V=A*H
V=(24 ft^2)*(4 ft)
V=96 ft^3
That’s literally the easy problem ever
