Step-by-step explanation:
x + 2x + 3x = 180°
6x = 180°
Therefore, x = 30°
2 x = 60°
3x = 90°
Hence, it is a right angled triangle.
<u>I'm assuming the 400 was supposed to be 4.00</u>
about 226 minutes
Multiply 1/6 by 1/6 by 1/6 essentially
(1/6)^3
1/216
Answer: 4
Step-by-step explanation:
Perpendicular lines have reciprocal slopes
20x-80=-20
-80 -80
20x= -100
/20 /20
x=-5
