27) 17
28)10
29) 8
Sorry that's all I know
Hopefully they're correct.
Explanation:
For the first one you know the angle is 90 degrees so the equation you re looking for would be 44 +(6x + 4) = 90 then you do 90-44 so you can get x on its own. and 90-44 equals 46 so your equation would now be 6x + 4= 46 you also have to take away the 4 so you do 46-4=42 so 6x=42 you know that the opposite of multiplication is division so in order to get x on its own you do 42/6 which equals to 7 so x=7 this got on with every other problem like this as long as you know the angle and the opposite inverse
27) 4x + 22= 90 28) 36+(5x+4)=90. 29) 38+(4+6x)=90
4x = 90-22 5x+4=90-36. 4+6x=90-38
4x=68 5x+4=54 4+6x=52
x=68÷4. 5x=54-4 6x=52-4
x=17 5x=50. 6x=48
x=50÷5 x=48÷ 6
x=10 x=8
