Let's figure out the other angle in each triangle.
A triangles' angles add up to 180°, so
XYZ has angles measuring 29, 54, and <u>97</u>°.
X'Y'Z' has angles measuring 29, <u>59</u>, and 92°.
All dilations are similar, meaning that if you shrink one down to the size of the other, they will be the same. Consider two triangles that have been dilated. The sides have changed but the angles are the <u>same</u>.
Triangle XYZ and triangle X'Y'Z' have angle measures that are not the same, therefore they are not similar. All dilations are similar, so X'Y'Z' cannot be a dilation of XYZ.
Answer:
Number 1 and 2
Step-by-step explanation:
For number 1, you have to distribute the 2 so 2*x=2x, and 2*4=8
That makes 2x+8 and number 2 is the only answer
Answer:
44%
Step-by-step explanation:
I took the test and got it right LOL goodluck
The margin of error is 1/√n, where n is the number of people
Margin of error = 1/√475 = 0.0458
Multiply by 100 to get percent:
0.0458 x 100 = 4.58% round to 4.6%
The answer is c.
Answer:
161
Step-by-step explanation:
We will use the math operation addition to find last year's number of floats. We know this year was 127 and was fewer than 34. So 127+34=last year's floats.
127+34=161
