If two planes intersect, they intersect in a line. This line consists of all common points of both planes.

The plane ABFE contains points A, B, F and E, because these points are in the name of the plane.

Points B, F, C and D lie on the plane BFCD.

As you can see points B and F are common points of planes ABFE and BFCD, this means that the line of intersection of these two planes is BF.

Answer: BF.

Solve for x. Round to the nearest tenth of a degree, if necessary.

MissTica

Answer:

x ≈ 54.8°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = $\frac{opposite}{adjacent}$ = $\frac{PQ}{QR}$ = $\frac{7.1}{5}$ , then

x = $tan^{-1}$ ( $\frac{7.1}{5}$ ) ≈ 54.8° ( to the nearest tenth )
