In figure (i) and (ii), Find the values of a, b and c.
Answers
Answer:
Step-by-step explanation:
(1) 60 + 70 = 180
130 = 180 180-130= 50
c= 50
(2) 55+60 = 180
115 = 180 180-115 = 65
a = 65
Answer:
(i). a=50 b=100 c=50 (ii). a=65 b=115 c=65
Step-by-step explanation:
In (i). to find a and b, and c you would have to add 60 and 70 together and you would get 130 we know that there are 180 degrees in a triangle so you would subtract 130 from 180 like this 180-130 which equals 50 so a=50 degrees. so now to get b you would add 30 and 50 to get 80 and since we know that there are 180 degrees in a triangle we subtract 180-80 which equals 100 so b=100 and to get c you would add 60 and 70 and you would get 130 and since we know that there are 180 degrees in a triangle you would subtract 180 from 130 and you would get 50 so c=50.
In (ii). to find a and b, and c you would have to add 60 and 55 and you would get 115, and since we know that there are 180 degrees in a triangle you would subtract 180 from 115 and you would get 65 so a=65 and to find c you would add 60+40+55 and you would get 155 and since we know that there are 180 degrees in a triangle you would subtract 180-155 and that equals 25 so that means that c=25 and to find b you would add 25+40 and you would get 65 so since we know that there are 180 degrees in a triangle then we would subtract 180-65 and we would get 115 so that means b=115.
