Answer:

the width of a rectangular is 3 cm

Step-by-step explanation:

Length L = 10 cm

Perimeter P = 26 cm

Width W = ?

perimeter = 2L + 2W

26 = 2(10) + 2W

26 - 20 = 2W

6 = 2W

W = 6 / 2

W = 3 cm

therefore, the width of a rectangular is 3 cm

Find cosØ if sinØ=-12/13 and tanØ>0. A) -5/12 B) -5/13 C) 12/5 D) -13/12

mestny [16]

Answer:

-5/13

Step-by-step explanation:

sin theta = opp / hyp

sin theta = -12 /13

we can find the adj side by using the pythagorean theorem

adj^2 + opp ^2 = hyp^2

adj^2 +(-12)^2 = 13^2

adj^2 +144 =169

adj^2 = 169-144

adj^2 = 25

Taking the square root of each side

adj = ±5

We know that it has to be negative since it is in the third quad

adj = -5

cos theta = adj / hyp

cos theta = -5/13

So i'm really confused how do you get 3 5/12 in this question? Manson bought 8 1/4 feet of wire. He cut off a piece of wire 3 5/

GaryK [48]

Answer:

r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x

Step-by-step explanation:

So cutting the wire of 12 m in length into two pieces, x and 12-x. The x side will be made into the square so that the square has sides x/4 and an area of (x/4)^2. This means the length of the wire 12-x will be the circumference of the circle. So if: r = π C , C = 12 − x , t h e n r = π ( 12 − x ) = 12 π − π x i hope this is correct
