Step-by-step explanation:
Answer:
x=53/9
Step-by-step explanation:
(x-2):5=7:9
9x-18=35
9x=35+18
9x=53
x=53/9
Answer: 33.85 mm
Step-by-step explanation:
Use trigonometry, tan equation
You are give the tan angle and adjacent side, you need to find the opposite side so
O
T A
Tan(72)= x/11
x= tan(72) x 11
x= 33.85
Answer:
∫
= 
Step-by-step explanation:
To find:
∫
Solution:
Method of substitution:
Let 
Differentiate both sides with respect to 

[use
]
So,
∫
= ∫
=
where
is a variable.
(Use ∫
)
Put 
∫
= 
Use 
So,
∫
= 
where 
Without using substitution:
∫
= ∫
= 
So, same answer is obtained in both the cases.
