Answer:
There are various types of angles based on their measure of the angles. The types are:
1. Acute Angle-An angle grater than 0° & Less than 90°.
2.Right Angle- An angle that is exactly 90°.
3.Obtus Angle-An angle more than 90°& less than 180°.
4 Straight Angle- An angle that is exactly 180°
5. Reflex Angle- An angle grater than 180° & Less than 360°.
6. Complimentary Angle- if two angles add up to measure 90°,then they as this....
7. Supplementary Angles- when two angles add up to 180° ,then they are known as this.....
7a. Vertical Angles- Angles which have a common vertex and the sides of the angle are formed by the same lines are known as this...
7b. Alternate Interior Angles- these types of angel present in pair. pair of interior angles present on the opposite side of interval.
7c. Alternate Exterior Angles-it is same to Alternate interior angle, just that just it is present on the exterior part.
7d. Corresponding Angles- Angles which are present in a similar position is called this.
2. 20x²+5x+ 19
3.. Substrate that then you know that answer.
4. -40+120+-14/ 60= -54+120/60= 66/60=33/20
( Find the L.C.M then add or subtract )
5a) N= {1,2,3,4,---------------}Starts from 1 not 0.
N*={0,1,2,3,4,5,6---------} the whole numbers are defined as positive integer including 0.
Z= {-------- -5,-4,-3,-2,-1,0,1,2,3,4,5,--------}
integers are combination of Zero, natural number and their additive Invers.
R= union of all numbers like N,N*,Z,Q excluding Imaginary number.
{------- -2,-1,-1/2,0,1,2,√2------}
