Answer:
see below
Step-by-step explanation:
side opposite 90 angle = x 
sides opposite 45 angle = x
the multiplication and division by should be self explanatory
1. x = 5, y = 5
2. v = 10, u = 10
3. x = 
, y = 
4. m = 5, n = 
5. a = 
, b =
6. a = , b =
its step 2 he did not subtract it right hope this helps and have a great day and get some sleep lol
Answer:
a=2.5
Step-by-step explanation:
3a-2.4=5.1 Add the like terms ( plus 2.4 cancels out -2.4)
+2.4 +2.4
3a=7.5 Now divide by 3
/3 /3
a=2.5
Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x + 2x + 2 + 3x + 4 = 180, that is
6x + 6 = 180 ( subtract 6 from both sides )
6x = 174 ( divide both sides by 6 )
x = 29
