Answer:
true
Step-by-step explanation:
2 angles are congruent when they they have the same measure
8cm cuase 32 is how área and your look for the base(b) and height (h) so you multiply 4 witch is your (h) and your lookin for you (b) and is going to be 8 cuase 4 times 8 is 32 witch is you area (a) so the answer is 8 cm for you (b)
You do 28/100 which is 0.28
You then multiply this by 21
28/100 x 21 = 5.88
Well, 7 times 5 is 35 so if that's the case there's your answer.
An example would be 1/3 as an exact answer and 0.33 as an approximate answer because 1/3 = 0.333..... - a recurring decimal where there are an infinite number of 3's. 0.33 would be correct to the nearest hundredth.
Radicals are exact answers :- like √2 , √5 . Approximate value for √2 is 1.414
