Answer:
c) the size of each exterior angles
Answer:
The correct answer is option <em>B. AA</em>
<em></em>
Step-by-step explanation:
Given two triangle:
and .
The dimensions given in are:
We know that the sum of three angles in a triangle is equal to .
The dimensions given in are:
We know that the sum of three angles in a triangle is equal to .
Now, if we compare the angles of the two triangles:
So, by AA postulate (i.e. Angle - Angle) postulate, the two triangles are similar.
by <em>AA theorem.</em>
<em>So, correct answer is option B. AA </em>
Answer:
1. B
2. Seven Hundred thousand nine hundred and four
Step-by-step explanation:
Answer: 14x^2 - 84x - 7
====================================================
Explanation:
The like terms 6x^2 and 8x^2 combine to 14x^2
The like terms -8x and -76x combine to -84x
Nothing pairs with the -7, so its stays as is.
Standard form is where we list the terms in decreasing exponent order. We can think of -84x as -84x^1 and the -7 as -7x^0. So 14x^2 - 84x - 7 would be the same as 14x^2 - 84x^1 - 7x^0. The exponents count down: 2,1,0.
The final answer is a trinomial since it has three terms. It is also a quadratic because the degree (highest exponent) is 2.
