Cos28=11/x
x=11/cos28
it will be c
Answer:
D) L=50 W=50
Step-by-step explanation:
Just "plug and chug" these numbers and see which doesn't work.
A is not it, 20+30=50 (then *2 because we need 4 sides not just 2) 50*2=100
B isn't it, 10+40=50*2=100
C ain't it either 49+1=50*2=100
D is the answer 50+50=100*2=200
Answer:
A. csc θ=1/sinθ
Step-by-step explanation:
From SOHCAHTOA,
sine = opposite/ hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
In a right angled triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the side opposite the angle. This is the inverse of sine , therefore:
Csc Ф = 1/ sinФ
Answer:
a=567 km+900 km
a=1,467 km
b=567 km+169 km
b=736 km
x^2/a^2+y^2/b^2=1
x^2/(1,467)^2+y^2/(736)^2=1
Step-by-step explanation:
