7x + 5x = 180
12x = 180
x = 15
Therefore, the 2 angles equal (7*15) and (5*15) which equals
105 degrees and 75 degrees

Answer:
As a proper fraction - 39/51 = 13/17
As a decimal number: 39/51 ≈ 0.76
As a percentage: 39/51 ≈ 76.47%
Step-by-step explanation:
Calculate the greatest (highest) common factor (divisor), gcf (gcd).
13/17 =
13 ÷ 17 =
0.764705882353 ≈
0.76
By precentage
0.764705882353 =
0.764705882353 × 100/100 =
76.470588235294/100 =
76.470588235294% ≈
76.47%
