Answer:
AG = 4
AH = 21
EC = 12
CH = 5
HE = 7
Step-by-step explanation:
<u><em>The complete question is</em></u>
The diameters of circles A, C and E are 32 cm, 24 cm and 14 cm respectively.
Which of the following statements are true? Select all that apply.
•AG = 4
•GC = 10
•AH = 21
•EC = 12
•EH = 5
•CH = 5
•HE = 7
The picture of the question in the attached figure
<u><em>Verify each statement</em></u>
1) AG = 4
we know that

----> radius of circle A
----> radius of circle C
substitute

therefore
The statement is true
2) GC = 10
we know that
----> radius of circle C
therefore
The statement is false
3) AH = 21
we know that

we have
----> radius of circle A

----> radius of circle C
----> radius of circle E
so


therefore
The statement is true
4) EC = 12
we know that
----> radius of circle C
therefore
The statement is true
5) EH = 5
we know that
----> radius of circle E
therefore
The statement is false
6) CH = 5
we know that

----> radius of circle C
----> radius of circle E
so

therefore
The statement is true
7) HE = 7
we know that
----> radius of circle E
therefore
The statement is true
Answer:
x = 2, y = 1
Step-by-step explanation:
- 7x + 5y = 19
- -7x - 2y = -16
Use the elimination method to solve the system of equations. Add the terms from top to bottom. 7x and -7x cancel out.
0 + 3y = 3
Divide both sides by 3.
y = 1
Substitute 1 for y into the first equation.
7x + 5(1) = 19
7x + 5 = 19
Subtract 5 from both sides.
7x = 14
Divide both sides by 7.
x = 2
