Answer: D) This triangle is a right triangle: 60^2+144^2 - 156^2 = 0
This is the same as saying 60^2 + 144^2 = 156^2
You would use the pythagorean theorem. In this case, a = 60, b = 144 and c = 156. The longest side is always the value of c. The order for the values of 'a' and 'b' do not matter. Convention usually has 'a' being the smaller of the two.
Answer:
93
Step-by-step explanation:
5+7 =12
12 x 6 = 72
72+21= 93
ACD and ACE are supplementary angles that need to equal 180 degrees
ACE = 180 -100 = 80 degrees.
Answer:
4√2 × 4√8 = 64, an integer.
Step-by-step explanation:
a) 4√2 × 4√8
First let's remember that a square root can be rewritten as a 1/2 exponent,
Therefore the expression we have can be rewritten as

We are going to write all numbers in their prime factor expressions:
<u>*Note: Remember that when we multiply two numbers with the same base but different exponents we sum up the exponents*</u>
<u>*Also, when we elevate one exponent to another exponent, we multiply the exponents*</u>

Therefore, the expression 4√2 × 4√8 = 64 and therefore is an integer
