Answer:

1:

180-(70+45)=65 degrees(3rd angle of triangle)

Angle 1 is 180-65=115 degrees.

2:

Angle 2 is 45 degrees as vertically opposite is also 45 degrees.

3:

180-(65+45)=70 degrees(third angle of lower triangle)

Its opposite will also be 70 degrees.

So, 3rd can be found as : 360-(70+110+70)=110 degrees

You can also say that 3 is vertically opposite of 110 degrees.

4:

180-65=115 degrees

5:

This is also 115 degrees as its vertically opposite angle to 4.

TRV = 72

V = 18  

see attachment

Step-by-step explanation:

CRT = 90 - C = 90 - 72 = 18

TRV = 90 - CRT = 90 - 18 = 72

V = 90 - C = 90 - 72 = 18

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric f
likoan [24]

Step-by-step explanation:

Let x be the length and y be the width of the rectangular plot.

The plot is bounded on one side by a river and on the other three sides by a single-strand electric fence. It means,

x+2y = 1500

x = 1500 - 2y ....(1)

We know that the area of a rectangular plot is given by :

A = xy ....(2)

Put the value of x from equation (1) in (2)

A=(1500-2y)y\\\\A=1500y-2y^2 .....(3)

For largest area, differentiate above area equation wrt y.

\dfrac{dA}{dy}=\dfrac{d}{dy}(1500y-2y^2)\\\\=1500-4y\\\\\text{Put}\ \dfrac{dA}{dy}=0\\\\1500-4y=0\\\\y=\dfrac{1500}{4}\\\\=375

Put the value of y in equation (1).

x = 1500-2(375)

= 750 m

Put the value of y in equation (3).

A =1500(375)-2(375)^2\\A=281250\ m^2

Hence, the largest area is 281250 m² and its dimensions are 750 m and 375 m.
