Answer:
A) 38.62 ft
B) 92.27 ft
C) 32.59 ft
Step-by-step explanation:
A) tan10= x/185
X= 32.62 + 6ft= 38.62ft
B) tan25= x/185
X= 86.27 + 6ft= 92.27ft
C) 92.27 - 6ft= 86.27
86.27+ 32=118.27
use inverse of tan tan-1= 118.27/185 in which you get 32.59ft
Answer:
x = 10
Step-by-step explanation:
3x - 9 = 21
add 9 on both sides:
⇒ 3x - 9 + 9 = 21 + 9
⇒ 3x = 30
divide 3 on both sides:
⇒
⇒ x = 10
to check answer, substitute x by 10 on the original equation:
⇒ 3x - 9 = 21
⇒ 3 x 10 - 9 = 21
⇒30 - 9 = 21
⇒ 21 = 21
