Answer:
see explanation
Step-by-step explanation:
multiply both sides by 2 to eliminate the fraction
2d = 2 t + a, that is
a + 2 t= 2d ( subtract 2t from both sides )
at² = 2d - 2 t= 2(d - t)
divide both sides by t²
a = 2(d - t) / t²
43.9 + x = 49.65
Subtract 43.9 from both sides:
49.65 - 43.9 = 5.75
The missing number is 5
The answer is 7.41666667
7 5/12= 89/12
Divide
=7.466666666667
adjacent exterior angles
x equals 80
y=3x
that is literally all
-18 and 15
-18 + 15 = -3
-18 x 15 = -270
