Answer:
x=57 degree
Step-by-step explanation:
Answer:
x = 2.2
Step-by-step explanation:
From the figure, we see that
Δ ABC
is similar to
Δ ADE
So we can say that the corresponding sides are proportional (ratio is equal).
From the similarity statement, we can say:
AB corresponds to AD
BC corresponds to DE
AB = 10
AD = 10 + 1 = 11
BC = 2
DE = x
Now, we can write ratios and solve:
![\frac{AB}{BC}=\frac{AD}{DE}\\\frac{10}{2}=\frac{11}{x}\\10x=2*11\\10x=22\\x=\frac{22}{10}\\x=2.2](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BBC%7D%3D%5Cfrac%7BAD%7D%7BDE%7D%5C%5C%5Cfrac%7B10%7D%7B2%7D%3D%5Cfrac%7B11%7D%7Bx%7D%5C%5C10x%3D2%2A11%5C%5C10x%3D22%5C%5Cx%3D%5Cfrac%7B22%7D%7B10%7D%5C%5Cx%3D2.2)
The value of x is 2.2
A. has 3 number that give it value
b. has 4 (even 0 add to its value)
c. has 3
D. has only 2
e. has 2 , both number add value
f. has 4 value
g also has 4, all numbers give value
hope this helps
