Let's represent h with the number of hours:
15h ≥ 200
h ≥ 200/15
h ≥ 40/3
h ≥ 13 1/3
He has to work at least 13 1/3 hours.
Answer:
the standard form of a linear equation required is B must be positive
Answer:
m=30°
n=35°
Step-by-step explanation:
So the right triangle's angles are 90 and 70 so m=30° because sum of angles in a triangle=180°
since the triangle with 110 degrees is congruent, that means the other blank angle is also N.
so if the sum of angles in a triangle is 180 degrees,
110+2n=180
2n=180-110
2n=70
n=35
