1st Question:
the answer is 85 because the angle measure does not change even if you rotate the figure.
2nd Question:
The answer is A) reflection across y-axis and translation 7 units down
3rd Question:
The first answer choice is correct because the figure increases/decreases in length on all side lengths and the angle measures stay the same.
Question 10: (on the test online)
The answer is 12*6 or 72 because 30 (a'b') / 5 (ab) is 6 giving you the scale factor for the dilation.
Question 11:
The answer is a dilation
Question 12:
The answer is a dilation and a translation because you first increase the size of the figure then move it down and to the right.
Hi there!
We can begin by multiplying by its conjugate:
Simplify using the identity:
Take the square root of the expression:
Multiply again by the conjugate to get a SINGLE term in the denominator:
Simplify:
Use the above trig identity one more:
Cancel out sinA:
Split the fraction into two:
Recall:
Simplify:
55,57,59
Let the smallest integer = x
171= (x) + (x+2) + (x+4)
171= 3x + 6
3x = 165
x= 55
therefore the integers are 55, 57, 59
