Answer:

CRT = 18

TRV = 72

V = 18  

see attachment

Step-by-step explanation:

CRT = 90 - C = 90 - 72 = 18

TRV = 90 - CRT = 90 - 18 = 72

V = 90 - C = 90 - 72 = 18  

RTC =TUS = SXW

9.88+(6,7-x) = 2,6 please help​
ddd [48]
Hello

First you have to remove your parenthesis and since there is a “+” in front of the parenthesis, the expressions remain the same. So:
9.88+6.7-x = 2,6

Now, you have to add the numbers. So:
16.58-x = 2,6

Next, you have to move the constant (x) to the right and change its sign since it changes side. So:
-x = 2,6-16,58

Now, calculate the difference:
-x = 13,98

And lastly, change the signs on both sides of the equation since - + - equals +. So:
x = 13,98



Hope you found this helpful

You learn more from failure than from success. Don’t let it stop you. Failure builds character.
