Answer:
11.8 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos 25 = x/ 13
13 cos 25 =x
11.78200123 =x
11.8 =x
By writing an equation you can easily solve this:
18+ X + 4X - 1 = 42
•we need the answer to 4X-1
1. put the parts that include the X parameter in one side and the integer numbers in one side :
X + 4X = 25
5X= 25
X= 5
2. 4X-1 —> 4x5-1 = 19
3x + 1 is the answer. Hope this helps you!
Answer:
the answer is C or 18x + 18y
