The first angle of a triangle is 8tº, the second angle is 3tº, and the third angle is 9tº. What is the measure of 9tº ? a 20º b 180º c 81º d 89º About the author Hadley
we know by angle sum property of the traingle 3t + 9t +8t = 180 20t = 180 t = 9 now 9t = 9×9 = 81° Hence option (c) thank you Reply
Answer: hey bro it’s a good question Step-by-step explanation: 8t+3t+9t =180. (Angle sum prop.) so t= 9° then 9t=81° Reply
we know by angle sum property of the traingle
3t + 9t +8t = 180
20t = 180
t = 9
now 9t = 9×9 = 81°
Hence option (c)
thank you
Answer:
hey bro it’s a good question
Step-by-step explanation:
8t+3t+9t =180. (Angle sum prop.)
so t= 9°
then 9t=81°
