Answer:
67.38°
Step-by-step explanation:
The diagonals of a rhombus intersect at their midpoints and make a right angle. They also divide the angles of the rhombus in two equal angles.
So, to find the acute angle of the rhombus, we can use the tangent relation of half this angle in the small triangle made when drawing the diagonals:
tan(angle/2) = 4 / 6
tan(angle/2) = 0.666
angle/2 = 33.69
angle = 67.38°
So the acute angle of the rhombus is 67.38 degrees.

Answer:
Step-by-step explanation:
By definition, tangent lines touch a circle at one point. This one point intersects the circle at a 90 degree angle.
In any circle, the measure of an inscribed angle is exactly half of the arc it forms. Since 
forms an arc labelled 244 degrees, the measure of angle 2 must be 
.
Angle 1 and 2 form one side of a line. Since there are 180 degrees on each side of the line, we have:
X=3. Just divide 12 by 4 thus giving you 3.
Answer:
A
Step-by-step explanation:
The line is parallel to y axis, so the equation is x = 5
