Since congruence and similarity for polygons is posted in a specific order, we know that angle A=angle F, side A=side F, die B=side G, and so on. Therefore, we have that angle C=angle H = 9x-7=5x+13. Subtracting 5x from both sides to separate the x using the subtraction property of equality, we get 4x-7=13. Next, we can add 7 to both sides to get 4x=20, and divide both sides by 4 to isolate the x and get x=5. Plugging that into angle C or angle H, we get that 9x-7=9*5-7=45-7=38=5*5+13.

The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π
410) + ( π4^2)
= 40π + 16π
= 56 π = 563.14
= 176 sq.units
Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
Answer:
about 201 ft of fencing
Step-by-step explanation:
Including the path the radius would be 32 ft. and the diameter is 64 ft.
C = πd where C is the circumference and d is the diameter.
So, C ≅ 3.14(64) ≅ 201 ft.
