Answer:
w = 4 cm
Step-by-step explanation:
recall that the area of a triangle is given by
A = (1/2) x base length x height
we are given:
A = 10 cm²
base length = 5 cm
height = w
substituting the values above into the equation,
A = (1/2) x base length x height
10 = (1/2) x 5 x w
20 = 5w
w = 20/5
w = 4 cm
Answer: The fraction x = 1/2 or its equivalent decimal form x = 0.5
================================================
Work Shown:
AE = 2*(BD)
4x+8 = 2*(4x+3)
4x+8 = 8x+6
8-6 = 8x-4x
2 = 4x
4x = 2
x = 2/4
x = 1/2
x = 0.5
note: the first equation is set up basically saying that AE is twice that of BD; put another way, BD is half as long as AE. This is one property of midsegments. Another property is that AE and BD are parallel.
another note: if x = 0.5, then AE = 4*x+8 = 4*0.5+8 = 10 while BD = 4*x+3 = 4*0.5+3 = 5, showing that AE is indeed two times longer than BD.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the angle is x
Imagine the right triangle with the angle x, with side opposite to angle x 15 ft and the adjacent side is 50 ft.
<u>Use trigonometry:</u>
- tangent = opposite / adjacent
- tan x = 15/50
- tan x = 0.3
- x = arctan 0.3
- x = 16.7° (rounded)
