Answer:
- Angle E corresponds to angle L
- The two triangles are similar
Step-by-step explanation:
<u>Angle E corresponds to angle L</u> because <u>the two triangles are similar</u> (and we know this becuase corresponding sides are proportional.
That would be 15/80=3/16 so it would be 3/16 or unlikely because it is less than half of 16
She is not correct.
The GCF for 2x^2 + 4xy + 8xy^4
is 2x
The first term does not have a 'y' in it so you cannot have a 'y' in the GCF.
The second and third terms both only have 1 'x', so you can only take out 1 'x', not 2.
The highest constant that all three terms have in common is a 2.
First, we need to find her current age. If she was 12 years old 3 years ago, her current age is 12 + 3 which is 15. If the ratio of Sarah's age to Keisha's age is 4:5 (Sarah's age is the 4 and Keisha's age is the 5).
If we take 15 and divide that by 5 (her ratio), then you get 3. Now multiply 3 by 4 to find Sarah's age. We get 12. Nine years from now, her age is 12 + 9 which is 21.
There is the answer. Sarah's age in 9 years is 21 years old. I hope this helps.
A.b=lallbl cos t
a.b=(-2*5)+(-1*4)+(3*7)
a.b=7
lal=√(25+1+49)=5√3
lbl=√(4+16+9)=√29
therefore:
7=5√3×√29 cost
cost=0.1501
t=arccos 0.1501=81.37°
