Any options for that question
Answer:a is 40 degrees
b is 140 degrees
Step-by-step explanation:
The given polygon has 5 irregular sides. This means that it is an irregular pentagon. The sum of the exterior angles of a polygon is 360 degrees
The exterior angles of the given pentagon are a, 75, 65, 60 and 120. Therefore
a + 75 + 65 + 60 + 120 = 360
a + 320 = 360
Subtracting 320 from both sides of the equation, it becomes
a = 360 - 320 = 40 degrees
The sum of angles on a straight line is 180/degrees. Therefore,
a + b = 180
b = 180 - a = 180 - 40 = 140 degrees
Yes, they cross each other and make an angle of 90° or right angle.
2. 64 = 2 × 2 × 2 × 2 × 2 × 2 2 |64
√64 = √2 × 2 × 2 × 2 × 2 × 2 2 |32
√64 = 2 × 2 × 2 2 |16
√64 = 2³ 2 |8
√64 = 8 2 |4
2 |2
3. No positive square root exists for -85 as it is a negative integer. The squares of a number is always positive.
