Let x be the unknown number.
The sum of x and seven hundred is 
Ten thousand times this sum is 
Answers are 2 and 3
supplementary angles and adjacent angles
(12ab)(3t) = (12 · 3)(abt) = 36abt
(goh) = 2(x^1/2)-1
(goh)(9) = 2(9^1/2)-1
= 2(3)-1
= 6-1
= 5
(goh)(9) = 5
Using the tangent rule:
Tangent(angle) = Opposite leg / Adjacent leg
We will use the 23 degree angle to solve for x.
Tangent(23) = X / 6
x = 6 * tangent(23)
x = 2.5
