Answer:
BE=AD
Step-by-step explanation:
X=20
180-77=103
so then simplify (6x-17)=103
6x=120
x=20
1) Tanθ= opposite/adjacent
θ=Tan-1(9/7)
θ=52.125 = 52 degrees
2) Cosθ= adjacent/hypothesis
θ=Cos-1(5/12)
θ=65.376 = 65 degrees
Answer:
1.1) Rational
1.2) Rational
1.3) Irrational
1.4) Rational
1.5) Rational
1.6) Irrational
Step-by-step explanation:
Rational means it can be represented as a fraction where the numerator and denominator are whole numbers and vice versa for irrationals.
Answer: AC : BC = 22 : 33 = 2 : 3
Step-by-step explanation:
Since we have given that
AB = 3x-4
AC= 2x+12
BC = 7x-2
And AB: AC = 1 : 2
and To show : AC : BC = 2 : 3
So, it becomes ,
So, AC: BC becomes:
Hence, proved.
