I don't see any question there ... just a bunch of pretty rulers.
I'm going out on a limb here, and I'm gonna assume that the question is "Identify the number to which the arrow on each ruler is pointing.".
If that's the question, you're welcome. If not, ignore everything I'm about to say.
Orphan ruler on page-1: 6 and 1/4
Rulers on page-2, starting at the top and working down:
6 and 3/8
1
3 and 5/8
2 and 1/2
7 and 3/4
4 and 7/8
5 and 1/8
9 and 1/2 .
If these answers are not helpful, remember: I'm the one who had to invent the question, and for the question that I invented, these answers are all correct !
Answer=42 degrees
Complementary angles= 90 degrees
90-48=42
<8 ,
<7 and <8 form a linear pair
Answer:
Scale factor = 3
Step-by-step explanation:
Using similar triangles
AT/AG = AB/AC
9/3 = x+10/3x-10
Cross multiply
3(x+10) = 9(3x-10)
Expand
3x+30 = 27x-90
3x-27x = -90 - 30
-24x = -120
x = 120/24
x = 5
For the larger triangle;
AC = 3x-10
AC = 3(5)-10
AC =15-10
AC = 5
AB = x+10
AB = 5+10
AB = 15
For the scale factor;
Since AT/AG = AB/AC
9/15 = 3/5
3*3/5*3 =3/5
Since the numerator and denominator of the larger triangle is multiplies by the same factor i.3 3. Hence the scale factor is 3
