Answer:
b = 60
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 63² = 87²
b² + 3969 = 7569 ( subtract 3969 from both sides )
b² = 3600 ( take the square root of both sides )
b = 
= 60
Answer:
56.5
Step-by-step explanation:
its just division
Answer:
<h2>A horizontal translation and a 180° rotation only.</h2>
Step-by-step explanation:
Notice those shapes are positioned as a reflection.
So, one way to map them onto is self is by rotating 180° and a horizontal translation. Or it could work if we translate it horizontally, the we reflect it vertically. Those transformations would map the strip onto itself.
Therefore, the second choice is the best answer.
Considering it's concept, it is found that the number of outcomes in the sample space is of 9.
<h3>What is the sample space of an experiment?</h3>
The sample space is the <u>set that contains all possible outcomes for an experiment</u>.
In this problem, there are 2 trials, each with 3 possible outcomes(red, blue or green), hence the <u>number of possible outcomes</u> is given by:
N = 3² = 9.
