= a^21b^24c^10
use the product rules for each set of () then multiply them together. when multiplying variables with exponents you just add them together like for a^3 * a^5 = a^8. (a^3 b^12 c^2)^2 = (a^6 b^24 c^4)
X/4 = -9
x/4 = -9/1
cross multiply
x = -36
Answer:
The vertex angle is 180-(60+75)=45.
k/sin75=900/sin45 so k=900sin75/sin45=1229km approx.
