Answer: 21, 63
<u>Step-by-step explanation:</u>
We need to find two geometric means between 7 and 189.
The Geometric Sequence is: 7, ____, ____, 189
Let's find r (common ratio):
We can see that the common ratio will be multiplied by itsely 3 times in order to get from 7 to 189:
7 r³ = 189

r³ = 27
∛r³ = ∛27
r = 3
Now that we know the common ratio is 3, we can multiply 7 and 3 to get the next term (21), and multiply that by 3 to get the third term (63), and multiply that by 3 as a check to confirm we get 189.
7 x 3 = 21
21 x 3 = 63
63 x 3 = 189
The completed Geometric Sequence is: 7, <u>21</u>, <u>63</u>, 189
Two angles are complementary: x + y = 90 (complementary = 90 degrees)
x = 2y
plug in 2y for x
2y + y = 90
3y = 90
3y/3 = 90/3
y = 30
plug in 30 for y
x = 2y
x = 2(30)
x = 60
x (the largest angle) = 60°
hope this helps
Step-by-step explanation:
in ∆TUW & ∆VWU
∠UTW = ∠UVW (data / given)
WU = WU (common sides) ∠TWU = ∠VUW (TW//UV alternate∠ )
so ∆TUW & ∆VWU are congruent
Answer this question by trigonometry.
Draw the rope at an angle of 33 degrees from the x axis.
You will find:
cosx = a/h
cos33 = a/290
a. = 243.21
