Answer:
4
Step-by-step explanation:
In similar triangles, corresponding angles will be in the same ratio
EA = DA - DE = 10 - 5 =5
Cross multiply,
x +3 = 6
Subtract 3 from both sides
x = 6 - 3
x = 3
x +1 = 3+ 1 = 4
Answer:
1) 188.4 in³
2)306 in³
3)210in³
Step-by-step explanation:
1) r = 5in h = 12in
5 * 12 * 3.14
2) L = 3 W = 8.5 H = 12
3 * 8.5 * 12
3) ( B = 5 W = 7 H = 12)
.5(5 * 7 * 12)
6.5 x 10 to the 10th power.
Answer:

Step-by-step explanation:
Using the trigonometric identity
tanx = , then
tanx =
x = ( ) =
Hence x = + kπ ( k ∈ Z )
Answer:
c. 4x + 20 = 140
Step-by-step explanation:
Perimeter = 140 feet
Width = L + 10
P = 2w + 2L
P = 2(L + 10) + 2L
P = 2L + 20 + 2L
P = 4L + 20
