Answer: a = 122*
The three angles added together form a circle or 360*.
Set a + b + c = 360 and solve for a
a + 66 + 172 = 360
Subtract 238 from both sides to get a
a = 122*

Answer:
a) x = 3.0625m
y = 45.9375 m
b) A = 140.68359375 m²
Step-by-step explanation:
Let x be the length
Let y be the width
2x + 2y = 98
x + y = 49
y = 3(5x)
y = 15x
x + 15x = 49
16x = 49
x = 3.0625 m
y = 15(3.0625) = 45.9375
A = xy = 3.0625(45.9375) = 140.68359375
Answer:
3 3/7
Step-by-step explanation:
7x+2v=48
2v. -2
-------
46
7x+46=48
-46. -46
