Answer:
a = 44 degrees
Step-by-step explanation:
- Triangle AOB is an isosceles triangle.
- Angle A and B are same.
- All three angles of a triangle are equal to 180 degrees.
angle 0 + angle a + angle b = 180 degrees
angle b = angle a
92 + a + b = 180 degrees
92 + 2a = 180 degrees
a = 44 degrees

Answer:
Step-by-step explanation:
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°.
-135° + 360° = 225°
Answer:
-32
Step-by-step explanation:
When using exponents, the base number is multiplied by that amount if times.
So, (-2)^5 =
-2 * -2 * -2 * -2 * -2 = -32
Hope this helps!
Step-by-step explanation:
Interior angle + Exterior angle = 180°.
Size of Interior angle = 180° - 360°/n.
Question 32:
Exterior angle = 72°
Interior angle = 180° - 72° = 108°.
Therefore 180° - 360°/n = 108°, n = 5 => 5 sides.
Question 33:
Exterior angle = 36°
Interior angle = 180° - 36° = 144°.
Therefore 180° - 360°/n = 144°, n = 10 => 10 sides.
