Step-by-step explanation:
Here we can see it is a quadrilateral so
x + 108° + 65° + 53° = 360° ( being sum of angles of quadrilateral)
226° + x =360°
x = 360° - 226°
Therefore x = 134°
Answer:
10 %
Step-by-step explanation:
15 mn = 1/4 h
We have :

Then the percentage that 15 mn represents of 5/2 h is :
0.1 × 100 = 10 %
Answer: x = -1/2
4x² + 4x + 1 = 0
⇔ (2x + 1)² = 0
⇒ 2x + 1 = 0
⇔ x = -1/2
Step-by-step explanation:
Distance = Speed x time = 162 x 3 = 486 miles/hour
Answer: 486 miles/hour
Answer:
False
Step-by-step explanation:
Angles a and b add to 180° (linear pair), so angle b is 68°.
