The GCF would be 14a, because 14a x 1 = 14a, and 14a x 2b = 28ab.
Answer:
y = -
Step-by-step explanation:
= ( cross- multiply )
4y = - 7 ( divide both sides by 4 )
y = -
Answer:
y=43 (alternate angle)
in triangle ADC
97+y+x=180(,sum of interior angle of triangle is 180)
x=180-97-43
x=40
answer:
x=74 y=27
steps:
triangle in the middle is
180-126 = 54
180-85 = 95
180-149 = 31
126=2x+1+31
126=2x+32
2x=94
x=74
126+2y=180
2y=54
y=27
