Answer:

12/sin90'=b/sin67'

12sin67'=bsin90'

b=12sin67/sin90'

Step-by-step explanation:

sister ,we can use the law of sines. since we have the angle of elevation and assume the wall makes a right  angle with the ground, our angle opposite the ground is 180-[90+23=67

hope this is  helpful for you

How do you figure out the reciprocal of a numer? E.g 5, 2/7 and 1&amp;2/5 ??
eimsori [14]
You need to multiply 1 and 5 plus 2. 
and for 5 2/7 it would be 5 times 7 plus 2.

So...
5 2/7= 37/7

1 2/5= 7/5

Answer:

(16)(1)                          => identity property of multiplication

2(3+7) = 2(3) + 2(7)    => distributive property

(2+6) + 3 = 2+ (6+3)   => associative property

9+0 = 9                      => identity property of addition

8 x 4 = 4 x 8              => commutative property
