The two triangles will be similar (same shape, and each side of one triangle the same multiple of the corresponding side of the other triangle), but not necessarily the same size.
The key word here is "similar;" be sure you understand what that means in trig.
Answer:
Step-by-step explanation:
Start by breaking up the question into parts:'always an odd number' . An even number is any number divisible 2 e.g. 2n, an odd number is always 1 higher or lower than an even number e.g. 2n+1 or something similar. Getting an answer at the end of working of this form will prove the theory'any two consecutive integers' means two numbers that are next to each other on the number line.To prove this, we can do this in terms of n i.e. n and n+1'the squares' square the two terms we have just written down to give n2 and (n+1)2The 'sum of the squares' tells us to add these two parts together. We would then hope to work through this and get something similar to the idea of 2n+1 or something similarn2+(n+1)2=2n2+2n+1=2(n2+n) +1. The first part of this is even because it is divisible by 2. By adding 1 it must become odd.
Answer:
9
Step-by-step explanation:
We have to solve in order to find out if Sam is correct
Remember PEDMAS:
For Multiplication, division and addition, subtraction, do what appears first left to right
Parenthesis
Exponent
Division
Multiplication
Addition
Subtraction
16 - 18 + (2+1)+2^3
Parenthesis first: 2+1 = 3
16 - 18 + 3 + 2^3
Exponent next: 2^3 = 8
Subtraction (it's on the left) : 16-18 = -2
Addition: -2 + 3 = 1
Addition : 1 + 8 = 9
<em>Sam is not correct, the answer is </em><em>9, </em><em>not 16.</em>
Hope this helps :)
Have a great day!
