Answer:
Rational numbers
Step-by-step explanation:
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.
Answer:
um does it have multiple choice by chance
Step-by-step explanation:
the sum of supplementary angles equals 180°
you can have an acute angle (less than 90°) + an obtuse angle (greater than 90°) equal to 180°
But you can also have a right angle (equal to 90°) + another right angle equal to 180°
Answer: (b) sometimes
This is all about right triangles, assuming the tower is not the leaning tower of pisa! The tower is our height of the right triangle, the base of our triangle is the distance Nadia is from the tower, and the reference angle is 30 (the base angle that is NOT the right angle). The tower is opposite this reference angle, and the side 60 is adjacent to this angle, so we will use the tangent ratio, the trig identity that relates the side opposite the reference angle to the side adjacent to it.
. Solving for x we get x = 60 tan(30°). On our calculators that gives us that x = 34.64. That's how tall the tower is.
