2-39
3-141
Step-by-step explanation:
180-39=141
1 and 3 look the same size and 2 looks the same as c (39°) so you jsut fill in for the letters
I'm pretty sure this is right
Seca(1-sina)(seca+tana)=1
Left hand side
=(1-sina) (seca +tana) / cosa
=seca +tana - sinaseca - sinatan / cosa
=seca + tana -tana -(sin^2a/cosa) / cosa
=(1/cosa - sin^2a/cosa) / cosa
= (1-sin^2a / cosa) / cosa
= (1-sin^2a)/ (cos^2a)
=1 (verified)
Answer:
The width of the yard is 20 ft
Step-by-step explanation:
In this particular question, we are asked to calculate the width of the rectangular front yard given the area of the front yard and the length of the front yard.
Mathematically, the area of the front yard is calculated by multiplying the length of the front yard by the breadth of the front yard.
Let’s say A = L * W
Substituting the known values, the unknown width would thus be:
W = A/L = 600 sq.ft / 30ft
W = 20 ft
Colors of light are each bent a different amount because each color has particular wavelength
