Complementary = angles add up to 90.
two angles are (x+3) and (4x-8)
Therefore:
90 = (x+3) + (4x-8)
Solve for x.
90 = (x+3) + (4x-8)
90 = 5x - 5
95 = 5x
/5 /5
19 = x
Therefore the value of x = 19
The answer is:
134
Explanation:
You have do do 10x14 first because of PEMDAS (Parentheses,Exponents,multiplication,division,addition,and subtraction)
Then you get 140-6 and get
134
-8/5 converted to a decimal is -1.6
-8/5 can make -1 plus the remainder
Hope this helps :)
