Answer:
≈ 27 ft
Step-by-step explanation:
using the tangent ratio in the right triangle formed by the building and the ground.
tan15° =
=
( multiply both sides by 100 )
100 × tan15° = ? , then
? ≈ 27 ft ( to the nearest whole number )
Answer:
3x+9 < - 42
Step-by-step explanation:
Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
Answer:
y = 3 - 4x
To find the y intercept let x = 0
y = 3 - 4(0)
y = 3 or ( 0 ,3)
Hope this helps.
