Answer:
BC 4 in
Step-by-step explanation:
The steps for construction;
- Using a ruler draw line AB 4 inches and label the end points A and B
- At point A , using a protractor, measure angle 60° and mark with point. Draw a line from A passing through this point extending to a length of 4 inches
- Mark that point C.
- Using the ruler, join point C and B and measure BC.
From calculation, length BC can be found by the formula;
------where a=b=4 in , cos A = cos 60°
BC = 4 in
Answer:
(
Step-by-step explanation:
We are given that two lines
and 
We have to find the intersection point of two lines
Let 
(equation 1)
(Equation 2)
Multiply equation 2 by 3 then subtract from equation 1
Substitute 
in the equation 1
Then, we get
Hence, the intersection point of two given lines is (
Answer:
7.9 is less than 8.0
Step-by-step explanation:
Source My head
length = 3234 m and width = 1614 m
let the width = w then length = 2w + 6
Perimeter = 2 ( length + width )
= 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12
given perimeter = 9696 the equating gives
6w + 12 = 9696
subtract 12 from both sides
6w = 9696 - 12 = 9684
divide both sides by 6
w = 
= 1614
width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m
1000000=PVe^(30x0.03)
1000000=PV x 2.4596
PV=406569.65974
