(7y is supposed to be 7x)

Mathematics
1 answer:
Andrei [34K]2 years ago
7 0

Answer:

Step-by-step explanation:

Angle E is (7x+27) because it is corresponding.

So, 7x+27+15x-5=180 (angle on a straight line is 180 degrees

22x+22=180

22x=158

x= 158/22 = 7.18'

Match each circumference to the corresponding radius or diameter of the circle. (All circumferences are approximate.) Tiles circ
Pavlova-9 [17]
We solve for the diameters of radius of the given circles by using the equation,
                                      C = πD
                    or               C = 2πr
where D and r are diameter and radius, respectively.

Solving,
      C = 34.54 units
                                D = C/π = 34.54 units / 3.14 = 11 units
                                r = C / 2π = 34.54 units/2(3.14) = 5.5 units

      C = 59.66 units
                                D = C/π  = 59.66 units/3.14 = 19 units
                                 r = D2 = 9.5 units
      C = 23.236 units
                                D = 23.236 units/3.14 = 7.4 units
                                 r = D/2 = 3.7 units
       C = 23.376 units
                                 D = 23.376 units / 3.14 = 7.4 units
                                    r = D/2 = 3.7 units
        C = 13.188 units
                                  D = 13.188 units/3.14 = 4.2 units
                                    r = D/2 = 2.1 units

LAST ATTEMPT IM MARKING AS BRAINLIEST!! (Pythagorean theorem )
vlabodo [156]

Step-by-step explanation:

The Pythagorean theorem is:

{c}^{2}  =  {a}^{2}  +  {b}^{2}

where c is the hypotenuse.

The two wires in the sketch are the hypotenuse so we just use the formula

let the wires=x

So:

{x}^{2}  =  {12}^{2}  +  {6}^{2}

{x}^{2}  = 144 + 36

{x}^{2}  = 180

x =  \sqrt{180}

x = 13.42 feet
