Answer:
x = 5 and y = 1 is the answer.
Step-by-step explanation:
(-5)(x+4y=1)
(-4)(-3x-5y=-10)
-5x + -20y = -5
12x + 20y = 40
———————
7x + 0 = 35
7x= 35
7x/7 = 35/7
x = 5
subtitution:
x= 5
x + 4y = 1
5 + 4y = 1
4y = 1 - 5
4y = 4
4y/4 = 4/4
y = 1

Answer:
x = 127°
Step-by-step explanation:
in each triangle, the value of each exterior angle is equal to the sum of its two non-adjacent interior angles..
47° + 80° = 127°
or
the third angle in the triangle:
180° - (47° + 80°) = 53°
exterior angle:
180° - 53° = 127°
