Answer: 125
Step-by-step explanation: The whole triangle equals 180 degrees and you have 2 two sides 25 and 30 so subtract those from 180 and you get 125.
Answer:
(i)
shifted left side by 5 units
(ii)
vertically stretch by 3 units
(iii)
shifted vertically downward by 2 units
Step-by-step explanation:
we are given

we can also write as

we can factor out 9

Firstly, we will identify parent function

step-1:
We can see that there is x+5 in place of x
so, f(x) will be shifted left side by 5 units
step-2:
3 is multiplied to sqrt
so, it is vertically stretch by 3 units
step-3:
-2 is added to y-value
so, it is shifted vertically downward by 2 units
Graph:
