Find the value of x - Secant and Tangent Angles in Circles

VladimirAG [237]

Answer:

C. 70°

Step-by-step explanation:

The inscribed angle marked 15° intercepts an arc that is double that measure, so the intercepted arc on the right is 2×15° = 30°.

The external angle marked 20° is half the difference of the intercepted arcs, so is ...

20° = (1/2)(x - 30°)

40° = x - 30° . . . . . . multiply by 2

70° = x . . . . . . . . . . . add 30°

The value of x is 70°.

The perimeter of a rectangular store receipt is ten and five-sixths inches. If three of the sides total eight and one-half inche

serg [7]

Answer:

The measure of the fourth side is $\frac{7}{3}$ .

Step-by-step explanation:

Given as :

The Perimeter of rectangular store = ( 10 + $\frac{5}{6}$ ) inches

The measure of three sides of rectangle = ( 8 + $\frac{1}{2}$ ) inches

So, The measure of three sides = length + breadth + length

I,.e 2 L + B = ( 8 + $\frac{1}{2}$ ) inches .....1

∵ perimeter = ( 10 + $\frac{5}{6}$ ) inches

So , 2 L + 2 B = ( 10 + $\frac{5}{6}$ ) inches

Or, 2 L + B + B = ( 10 + $\frac{5}{6}$ ) inches

Or, ( 8 + $\frac{1}{2}$ ) + B = ( 10 + $\frac{5}{6}$ )

or, B = ( 10 + $\frac{5}{6}$ ) - ( 8 + $\frac{1}{2}$ )

Or, B = 10 - 8 + ( $\frac{5}{6}$ ) - $\frac{1}{2}$

or, B = 2 + $\frac{5-3}{6}$

or, B = 2 + $\frac{1}{3}$

∴ B = $\frac{6 + 1}{3}$ = $\frac{7}{3}$

Hence The measure of the fourth side is $\frac{7}{3}$ . Answer
