Since the sum of the angles of a triangle = 180°
Then (2x)º + (x + 60)º + (3x)º = 180°
(6x)° + 60° = 180°
(6x)° = 180° - 60°
x = 120° ÷ 6
∴ x = 20

Answer:
84
Step-by-step explanation:
140% of 60 = 60 times 140% = 60 × 1.4 = 84
Standard form : Ax + By = C
y = 2/3x + 1
-2/3x + y = 1....multiply by -3
2x - 3y = -3 <=== standard form
To calculate it use pythagoras: a^2+b^2=c^2
7^2+10^2=49+100=149
calculate the square root:

so the diagonal is about 12.2 inches long
