tan 44 = h/ x
x = 15 ft * sin 26
so
h = x * tan 44
= (15 ft * sin 26) (tan 44 )
so the anser is D

ANSWER
EXPLANATION
From the given information, Elena chooses a number from 1 to 10.
The sample space is
S={1,2,3,4,5,6,7,8,9,10}
n(S)=10
The numbers greater than 5 are:
E={6,7,8,9,10}
n(E)=5
The probability that, she chooses a number greater than 5 is:
Substitute the values,
Given:
To find:
The length of QR.
Solution:
We have,
Then, (CPCTC)
Divide both sides by 4.
Similarity,
(CPCTC)
Divide both sides by 2.
Now,
Therefore, the correct option is d.
