Find the ratio of the area of triangle xby to the area of triangle abc for the given measurements, if

by = 2, bc = 4

1/3
1/4
1/2

B. 1/4

Step-by-step explanation:BY/BC=2/4=1/2

Area ratio:

Area of triangle XBY / Area of triangle ABC = (BY/BC)²

=(1/2)²

=1/4

So the answer is B.  1/4

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
