Answer:
m∠C = 122°
Step-by-step explanation:
Opposite angles of a quadrilateral inscribed in a circle are supplementary. This means
m∠A + m∠C = 180°
m∠B + m∠D = 180°
To find angle C we need to find x, then subtract m∠A from 180°
x+20=3x
20=2x
x=10
Now we substitute 10 in for x
m∠A=2(10)+38
m∠A=20+38
m∠A=58°
Now we subtract this value from 180.
m∠C=180-58
m∠C=122°
Based on the expression and the values of a, b, and c, the value of the expression is 6 ¹/₆.
<h3>What is the expression's value?</h3><h3 />
The expression is:
= (a + 2bc) / 3a
Solving gives:
= (4 + (2 x -5 x -7)) / (3 x 4)
= (4 + 70) / 12
= 74 / 12
= 6 ² /₁₂
= 6 ¹/₆

Given:
The length of a string in yards is a function f(n) of the length n in inches
To find:
The function rule for the given situation.
Solution:
We know that,
12 inches = 1 yard
1 inch =
yard
n inches =
yards
It is given that the length of a string in yards is a function f(n) of the length n in inches. So,

Therefore, the required function for the given situation is
.
