Answer:
Step-by-step explanation:
This is an Isosceles triangle, two of the angles are equal
A triangle has how many degrees in it? 180°
A two angles that form a line also has 180°
Think of two right angles 90° + 90° = 180° (I wish i could draw on this)

<u>90°|90°_</u>
<u />
angle SRT = angle STR = 20°
angle STR + angle STU = 180°
20° + angle STU = 180° subtract 20° from both sides
angle STU = 160°
angle STU = 4x subs in 160°
160° = 4x divideboth sides by 4
40° = x <---------------- FINAL ANSWER D

Answer:
C
Step-by-step explanation:
Due to the fact that you are surveying more people and that those people are differentiated there will be a more representative answer rather than a biased one.
Here is the answer- 297. I hope this helps! I solved this by changing the fractions so that they had the same denominators.
Answer:
D: 108 cm
Step-by-step explanation:
Use your test-taking skill to eliminate the other answers. The perimeter of the given square is (9 cm)×4 = 36 cm. None of the other answers can possibly be correct for a square that is made larger by dilation.
_____
Every linear measure is increased by the dilation factor. If side lengths are multiplied by 3, then the perimeter is multiplied by 3.
... 3×36 cm = 108 cm
____
Another way to ge there is to realize the side length is multiplied by 3, so in the larger square is 3×9 cm = 27 cm. The perimeter is the the sum of the 4 equal sides, so is ...
... 4×27 cm = 108 cm
