Answer/Step-by-step explanation:
1. <B is an inscribed angle in a circle which intercepts arc AC.
Therefore, m<B = ½ of m<AC
B = ½ * 128° = 64°
x = 180 - (64 + 43)
x = 180 - 107 = 73°
2. The circle given shows two chords intersecting at point H.
According to intersecting chords theorem, the products of the segments formed by one chord equals the product of the segments formed by the other.
Therefore,

Solve for x

Divide both sides by 10

Answer:
<u>x</u>
Step-by-step explanation:
Let's simplify the LHS so it can be equated to the RHS.





Hence, the missing term in the numerator of the answer is <u>x</u>
Product= multiplication
s= a number
is= equal sign
3/4s= 3/5
divide both sides by 3/4
s= (3/5) / (3/4)
to divide fractions, multiply by the reciprocal/inverse of 3/4
s= 3/5 * 4/3
multiply numerators; multiply denominators
s= (3*4)/(5*3)
multiply within parentheses
s= 12/15
simplify by 3
s= 4/5
ANSWER: 4/5
Hope this helps! :)
your answer is C. plug in -1 for x and Y. 4(-1) + (-1). now add... -5. -5 is greater than -6 which is a ordered pair we needed to make this true
