If 2x + 6 = 90°, then x = 42.
true or false?

It is true because they both equal 42 =True

True, The problem is 2x+6=90 Using the equation and substituting x for 42 You use PEMDAS Parentheses Exponents Multiplication Division Addition Subtraction In this equation you substitute like I said above So the equation should look like 2(42)+6=90 You use PEMDAS but since there are no parentheses or exponents you skip to multiplication. So 2×42 is 84. Then you continue with what is left so now you have 84+6=90 84 plus 6 is 90 So the answer is TRUE. I hope this was helpful :) Goodluck!
