Answer:
Step-by-step explanation:
using pythagoras theorem
a^2+b^2=c^2
7^2+KL^2=25^2
49+KL^2=625
KL^2=625-49
KL=
KL=24
take M as reference angle
using tan rule
tan M=/opposite/adjacent
tan M=KL/ML
tan M=24/7
Simplify the expression 5³×5‐⁵

Answer:
r = -
Step-by-step explanation:
The n th term of a GP is
= a₁
where a₁ is the first term and r the common ratio
Here a₁ = 18 and a₆ = - , then
18 = -
( divide both sides by 18 )
= -
( take the fifth root of both sides )
r = = -
