Answer:
70
Step-by-step explanation:
An angle formed by 2 tangent lines is equal to one half the measure of the major arc minus the measure of the minor arc.
we are given the minor arc ( 110 ) however we are not given the major arc.
Because circles make a 360 degree rotation we can find the major arc by subtracting the measure of the minor arc from 360
Thus, major arc = 360 - 110 = 250
Now that we have identified the major and minor arc we can find x
Recall that x = 1/2 ( major arc - minor arc )
Thus, x = 1/2 ( 250 - 110 )
250 - 110 = 140
140 / 2 = 70
Hence, x = 70
Answer:
b
Step-by-step explanation:
angle b = angle e = 90 (given) R
if ac = df H
bc = ef (given) S
<span>Rational
expressions are defined as the quotients of two integers in which the
denominator does not equal to zero. Thus, the numerator and denominator would
be polynomials, which is a form of a system analogous to the integers under the
operation of addition, subtraction and multiplications. Therefore, the key
numbers of rational expressions are its variables in the numerator and/ or
denominator.</span>
