answer = 9c²d^8
(3cd^4)^2
=(3)^2 × c^2 × (d^4)^2
=9×c^2×d^8 ----law of indices (a^m)^n = a^mn
=9c²d^8
So hmm check the picture below
so.. that means the interior angle at the vertex R is 180 - 82, or 98
now, the sum of all interior angles of a polygon is 180(n - 2)
where "n" is how many sides are there in the polygon
this is a pentagon, so 5 sides, so, the sum of all the interior angles is then
180( 5 - 2)
180(3)
540
that means that
98 + 82 + c + 116 + c = 540
2c + 98 + 82 + 116 = 540 <----- solve for "c"
Answer:
We get that √48 = 2⋅2√3. Lastly, step three says to simplify, so we go ahead and multiply the 2⋅2 outside of the square root to get 4√3. That's it! We get that √48 = 4√3.
Step-by-step explanation:
Answer:
x=4
Step-by-step explanation:
21x+6=90(alternate angles)
21x=90-6
x=94/21
Therefore, x=4
