Answer:

Step-by-step explanation:
Look at the picture.
Use the Pythagorean theorem for calculate the length of CA:

We have

Substitute:

subtract 100 from both sides

ΔADC and ΔACB are similar. Therefore the corresponding sides are in proportion:

We have:

Substitute:

cross multiply
divide both sides by 5

If you mean the length of segment CD, then use the proportion:

Substitute:

Answer: 10202
Step-by-step explanation:you are right! I’m pretty sure!
H(3)=10
H(10)=101
H(101)= 10202
2x + 3y = 45
x + y = 10......y = 10 - x
2x + 3(10 - x) = 45
2x + 30 - 3x = 45
-x + 30 = 45
-x = 45 - 30
-x = 15
x = -15 <====
and y = 25
Answer:
x = 6
Step-by-step explanation:
If A, B and C lies on a straight line in order, then;
AB+BC = AC
x+12+2x-4 = 26
x+2x+12-4 =26
3x+8 = 26
3x = 26-8
3x = 18
x = 18/3
x = 6
Hence the value of x is 6
