Answer: 17.3ft

Step-by-step explanation:

Using sine rule

((sin base)/20)= ((sin suzy)/y)

suzy= 180-(90+30)= 180-120=60

((sin 90)/20)= ((sin 60)/y)

(1/20)= (0.8660/y)

Cross multiply

y= 0.8660*20

y= 17.3

Answer:

13/18

Step-by-step explanation:

6.5 · 1/9 = 6 5/10 · 1/9

6 1/2 · 1/9 = 13/2 · 1/9
13/2 · 1/9 = 13/18

Rewrite using a single positive exponent

Korolek [52]

Answer:

9³

Step-by-step explanation:

We need to find the value of $\dfrac{9^5}{9^2}$ .

We know that,

$\dfrac{x^a}{x^b}=x^{a-b}$

Here, a = 5 and b = 2.

So,

$\dfrac{9^5}{9^2}=9^{5-2}\\\\=9^3$

So, the answer to the given expression is 9³.
