Answer:
1
Step-by-step explanation:
Angles a, b, and c are all 60°. A triangle’s angles add up to 180, and if the triangle is equilateral, each angle must be 60 (180/3). Angle d is 120° because b and d form a supplementary angle (180°), so 180-60 is 120. Angle e and f and 30°. Angles c and e form complementary angles (90°), so 90-60=30. For f, if the triangle adds up to 180, 180-120-30 = f. The 120 comes from d and the 30 comes from e. This leaves f as 30.
You can use the equation x+(x+1)=73 in this situation.
This would equal to 2x+1=73, which makes 2x=72. X would be 36, and 36+37 is 73.
Basically your answer would be any two integers, starting from 37 and up.
Ex. 37+38=75 or 38+39=77, and so on.
Only positive numbers can apply to this question because any number consecutive to a negative number would *definitely* be less than 73.
