Answer:
Angles in a triangles add up to 180°
Respectively 1 : 2 : 3 is going to be 1 x , 2 x and 3 x so,
1 x + 2 x + 3 x = 180°
⇒ Simplify
6 x = 180°
⇒ Divide by 6 on both sides to isolate x
x = 30°
Since the ratio was 1 x : 2 x : 3 x and x is 30°,
30 : 60 : 90
And since there is a 90° angle, it is a right - angled triangle
$6!
10% is $3, you just move the decimal to the left one space, and that's 10%, so double is $6
30 divided by 3. Their are 3 sets of ten by 30 positives
The answer is D because linear functions represent y=mx+b and D is the one that represents it.
2.98=100%
2.32/2.98 = 0.78
0.78*100=78%
The percent of decrease was 22%.
