Answer:
Choice D, 20 inches.
Step-by-step explanation:
The Pythaogorean theorem tells us that the hypotenuse of a triangle, c, can be found by taking: c = . In this case, a = 3 and b = 4. So:
c =
c =
c =
c =
c = 5
The sides of a rhombus are all equal. Given that one side is equal to 5, we can simply multiply 5 by 4 to get 20. The perimeter is 20 inches.
Answer:
x = -1.6
Step-by-step explanation:
.5x - 3 = 3x + 6 - 5
.5x - 3 = 3x +1
-2.5x = 4
x = -1.6
The length of an arc is given by (θ/360)2πr, where θ is the angle subtended by the arc at the center and r is the radius.
The angle θ in this case is 270°, while the radius is 7 feet, diameter is 14 feet
Thus the length of the of the cable will be;
=(270/360)× 22/7×14
= 0.75 × 44
= 33 feet
I can answer only 1st coz I have no idea about 2nd problem..
Here Hypotenuse is 5
a =x
b =4
c = 5
5 square =x square +4 square..
25 =x square+16
25 -16 =x square
9 =x square..
√9 = x
3 = x..
