Answer:
30-17=13 pounds that's the answer
Answer:
70
Step-by-step explanation:
add 19 twice and 16 twice to get your answer.
The error is not there. The error is step 4. -34 becomes positive so it is not -51 it's 17. So the answer is 40/17
Because it's iscosceles, angle 1 is similar size to the angle on the right leg.
∠1 = 67°
The sum of interior angles in trapezoid equals to 360°.
And because it's iscosceles, the upper angles are in the same size. We can write it as,
the sum of angles = 360°
67° + 67° + ∠2 + ∠2 = 360°
134° + 2 × ∠2 = 360°
2 × ∠2 = 360° - 134°
2 × ∠2 = 226°
∠2 = 113°
Final answer
∠1 = 67°
∠2 = 113°
1. 100000
2. 0.000000000001
3. 400
