Answer:
Angle 1: 55
Angle 2: 110
Angle 3: 15
Step-by-step explanation:
Angle 1: x
Angle 2: 2x
Angle 3: x-40
The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).
I don’t think it is, sorry I’m not 100% sure, good luck though
1/3 * 7/9 kg = (1 * 7)/(3 * 9) kg = 7/27 kg
He used 7/27 kg of sugar.
3t-7=5t
-3t -3t
-7 = 2t
/2 /2
t = -7/2
Plug it in to 6t, so it is 6(-7/2) = -21
It is very simple you will just multiply it by half
4.32 × 10^-4 /2
=2.16 × 10^-4
The answer is D.
