tan(angle) = opposite leg / adjacent leg
tan(angle) = 26 / 14.5
angle = arctan(26/14.5)
angle = 60.85 degrees.
The answer is C.

Ok let us see it this way:
If x is the measure of the angle we require
<span>The complement is 90 - x </span>
<span>one half of the complement is therefore 0.5(90 - x)
</span><span>18 degrees less than one half of the measure of the complement is
0.5(90 - x) -18
</span>I hope this can be of good use
opposite sides and diagonals of a parallelogram are equal
+ diagonals of a parallelogram meet eachother in the middle so:
10x+14=x+77
10x-x=77-14
9x=63
x=63÷9
x= 7
y+8=4y-19
y-4y=-19-8
-3y=-27
y=-27÷-3
y=9
2z+3=37
2z=37-3
2z=34
z=34÷2
z=17
