What ? answer? dont know which one
Volume of a Pentagonal Pyramid 5/6 <span>abh
Given,

Answer:
answer maybe x^2 + 3x - 28
explanation
first of all this is how any number of such a kind shud be written
ax^2 + bx + c
so that rearrange it
7x^2 + 3x -4
but I personally would go further to put it like this
x^2 + 3x - 28
both answers are the same so but maybe one is more considered since ur qn requires standard form
in case of any misunderstanding plizzz reach out for further explanation
hope this helps
Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° = 
, sin30° = 
, then
cos30° = 
= 
= ( cross- multiply )
2x = 20
× = 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
