Angle 1 is a right angle =90 °
so 5x-85=90
5x=90+85
5x=175
x=35
Answer:
D
Step-by-step explanation:
The interquartile range is the difference between the last dot on the box and the first dot on the box.
20 - 40:
150 - 110 = 40
50 - 70:
125 - 95 = 30
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:
False

They don't look alike
Answer:
r≈12.89
Step-by-step explanation:
Using the formula
C=2πr
Solving for r
r=C
2π=81
2·π≈12.89155
