Answer:
V = 3 x 14 x 6 1/4 = 3 x 14 x 25/4 = 1050/4 = 525/2 = 262 1/2 ft
=> Option D is correct
Hope this helps!

Well we know that all the sides are congruent so you can use SSS
There are two sides and one angle that is congruent therefore SAS
You have pairs of legs that are congruent so LL
Lastly we know that JK and QR are congruent so you get HA
Hope this helps :)

Answer:
x = 24.5
Step-by-step explanation:
There are two similar triangles. In similar triangles the sides are in proportion.
Let's name big triangle as triangle 1 and small triangle as triangle 2.
The sides of the big triangle:
27 as base and the longest side (x + 7)
The sides of the small triangle:
base = 27 - 6 = 21
longest side = x
We need to find the value of x using proportion.
27/21 = (x + 7)/ x
By cross multiplying, we get
27(x) = 21(x + 7)
27x = 21x + 147
27x - 21x = 147
6x = 147
Dividing both sides by 6, we get
x = 147/6
x = 24.5
The value of x = 24.5
Hope you will understand the concept.
Thank you.
Answer:
Grade≥69(at least 69)
Step-by-step explanation:
(77+69+65+x)/4=70
x=69
so he must get 69 or more
