He didn’t follow PEMDAS which is the an acronym for the order of operations. according to pemdas the first step is parenthesis (which is the p in pemdas) there fore the first step is to add the 1 and the 2
then since there are no exponents you multiply so you multiple 5(3) which is 15
then you can add all the number left to right
so 15+2+3= 20
so the answer is 20
hope this helped
let me know if you have any questions

Step-by-step explanation:
The height of the door is given as 10 feet. The bottom 1/2 has a height of 5 feet.
The width of one door = 12/2 = 6 feet.
The value for x^2 = 5^2 + 6^2
x^2 = 25 + 36
x^2 = 61
sqrt(x^2) = sqrt(61)
x = 7.81
The closest value = 8

Step-by-step explanation:
55° for both. A triangle always adds up to 180 degrees. If A and C are both equal then it's pretty straightforward. 180 - 70 = 110. Split the other two angles in half. 110 ÷ 2 = 55. BAM!
