Hello!
<u><em>Explanation: Addition property of equality is adding the same number to both sides of an equation does not change the equation.</em></u>
<u><em>a+c=b+c</em></u>
<u><em>First, add by 23 both sides of an equation.</em></u>
<u><em>y-23+23=-5+23</em></u>
<u><em>And then, simplify.</em></u>
<u><em>23-5=18</em></u>
<u><em>It changes negative to positive sign.*</em></u>
<u><em>Final answer is y=18</em></u>
<u><em>Hope this helps!</em></u>
<u><em>Thanks!</em></u>
<u><em>Have a great day!</em></u>
Part a)
we have that
<span>√72
</span>√72-----> √(2*36)=√2*√36 is not 2*√36------> this is the error
√2*√36=√2*√6²-----> √2*(6)----> 6√2
<span>
</span><span>alternative method</span><span>
72 is equal to-------> 2</span>³*3²
therefore
√72-----> √[2³*3²]----->√ 2³*√3²-------> (2√2)*(3)-----> 6√2
Part b)<span>Estimate the square root of 72 to the nearest tenth
</span>
we know that
√2 is equal to 1.41
so
√72=6√2------> 6*1.41-----> 8.46----> 8.5
the answer Part b) is 8.5

The number of different triangles that can be drawn that have the same angle and side measures will be 2.
<h3>What is an isosceles triangle?</h3>
It should be noted that an isosceles triangle simply means a triangle that has two sides that are of equal length.
In this case, the number of different triangles that can be drawn that have the same angle and side measures will be 2. The angle is 75° and side length is 12cm.

Answer:
9.17 feet
Step-by-step explanation:
Use the Pythogoras theorem, a^2 + b^2 = c^2
you are give c and b ( because one side is slanted, so c) so rearrange to get
c^2-b^2 = a^2
10^2 - 4^2 = 84
square root 84 to get
