Answer:

option c is the correct answer

Step-by-step explanation:

∠YXZ+117°=180°

∠YXZ=180°-117°

∠YXZ=63°

63°+36°+∠YZX=180°(sum of angles is 180)

99°+∠YZX=180

∠YZX=180-99

∠YZX=81

A circular path 4 feet wide has an inner diameter of 550 feet. How much farther is it around the outer edge of the path than aro

Softa [21]

Answer:

$L_c=25.12ft$

Step-by-step explanation:

From the question we are told that

Width of circular path $w_c=4ft$

Inner Diameter $d_i_n=550ft$

Outer diameter $d_{out}= 550 +2*4$ (inner diameter + 2 circular path width)

$d_{out}= 550 +8\\d_{out}= 558ft$

Generally the equation for inner circumference of the circle $C_1$ is mathematically given by

$C_1=\pi d_{in}$

$C_1=3.14*550$

$C_1=1727ft$

Generally the equation for outer circumference of the circle $C_2$ is mathematically given by

$C_2=\pi d_{out}$

$C_2=3.14*558$

$C_2=1752.12ft$

Generally the difference in length of the two circumference $L_c$ is mathematically given by

$L_c=C_2-C_1$

$L_c=1752.12-1727$

$L_c=25.12ft$

3. A Fahrenheit thermometer reads 63°F. If the temperature increases 10°F, to the nearest degree, what is the new temperature C,

Umnica [9.8K]

Formula to convert F to C:

(F -32) x 5/9

F = 63 + 10 = 73

73-32 = 41

41 x 5/9 = 22.77777

Rounded to the nearest degree = 23 C
