Answer:

l = 33 feet

Step-by-step explanation:

Let length be l.

Width, b = 2l-1

Perimeter of the room, P = 196

We know that the perimeter of the rectangle is given by :

P = 2(l+b)

196=2(l+2l-1)

98=3l-1

Adding 1 both sides.

98+1=3l-1+1

3l=99

l = 33 feet

So, the length of the room is 33 feet.

Let a = 0.9876 and b = 0.9887 with N = 2, calculate the midpoint.

rodikova [14]

Answer:

For a=0.9876 and b=0.9887 mid point will be 0.98815

Step-by-step explanation:

We have given a = 0.9876 and b = 0.9887

And N = 2

We have to find the mid point

For finding mid point we know that formula

Midpoint $=\frac{a+b}{2}$ , here we have given a=0.9876 and b = 0.9887

So midpoint will be $=\frac{0.9876+0.9887}{2}=\frac{1.9763}{2}=0.98815$

So for a=0.9876 and b=0.9887 mid point will be 0.98815

Answer:AGC and DGH are opposite angles.

Step-by-step explanation:

So, Y+10=3x-40

Y-3x=-50-(1)

3x-40=2x

3x-2x=40

x=40

Y-3x40=-50

y-120=-50

y=-50+120

y=70

Hence, the answer is A 70°
