Answer:
x = 41.2
Step-by-step explanation:
Assuming the dotted line at the top is parallel to the segment with length x, it follows from the alternate interior angles theorem that the interior angle of the triangle (marked in diagram) is also 27º.
Using SOH-CAH-TOA, we get that tan(27º) = 21/x, so x = 21/tan(27º), which is approximately equal to 41.2.
Answer:
D): -2.14 < |-2.8| < √10
Step-by-step explanation:
• Always a negative value is less than a positive value.
• |-2.8| = 2.8, but it is less than √10
• √10 = 3.162 which the greatest

Is it multiple choice? An example would be 2, 8, 32...
Answer:
A negative exponent involves taking the inverse of the number, then multiplying it by itself once it's in the denominator of the fraction.
