The three interior angles of any triangle add to 180 degress. Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
Answer:
<em>Explanation below</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
There are two basic relations of angles we need to recall:
- Supplementary angles add up to 180°
- Internal angles of a triangle add up to 180°
Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:
c = 180 - ( a + b )
Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus
c = 180 - d
From the two relations above, it follows that:
a + b = d
What r the options so i can get an idea
Step-by-step explanation:
1. 48 decide by 16 = 3 per min
2. Decide by 7 you will get 5:2
3. 24 per hour so 3 hours is 3 times 24 which is 72
4. 5cm per hour
5. 175:326.
6.1080 decide by 9 you get 120
120 times 13 is 15607.
7. 2520 decide by 9 is 280
Sara got 560 while Hina got 19608.
8. Ali is the fastest. He can fold 8 in a minute
9. I dont understand your question
10. A is 3
