The phrase "horizontal angle" is correct and usable in written English.
It refers to the measurement of an angle on a horizontal plane. Example: The surveyor carefully measured the horizontal angle between the two buildings before constructing the new road.
One theory holds that birds find the right direction by determining the horizontal angle measured on the horizon from the Sun's projection.
By Dana Goodyear August 12, 2008 A lot of the streetlights you see in Los Angeles seem to be those tall slim vertical fellows, with the lantern projecting at a horizontal angle, like the mouthpiece on a telephone headset.

Flatseats.com compares first- and business-class "lie-flat" beds and (nearly horizontal) "angled flat-seats".
By repeating the measurement as many as 16 times and averaging the results, horizontal angles can be measured more closely; in geodetic surveying, measurements of all three angles of a triangle are expected to give a sum of 180 degrees within one second of arc.
In Equation 3, θ and ϕ are the vertical and horizontal angles of the beam width, respectively.
The T-axis has nearly horizontal dip and the dip of P-axis is distributed from vertical to horizontal angles in the portion deeper than ~8 km.
Special care was needed to acquire sharp and well-focused images from different locations covering a range of vertical and horizontal angles.
