Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°
(2,3) I think. I'm not in Algebra 1, so yeah
Answer:
30 Bows
Step-by-step explanation:
Every yard is 3 feet, and each bow calls for 1/3 of a yard, so a foot per bow.
So you can make 10 yards, 30 feet by multiplying by 3, and then its pretty straight forward from there. 30 / 1 = 30 Bows
Answer:
62
Step-by-step explanation:
Angle-A and angle-B are alternate interior angles with parallel lines cut by a transversal. That tells you that the two angles are EQUAL. So you can write
8x + 78 = 2x + 114 ,
and it should all be smooth sailing for you from that point.
