Solve R=(88.99)^2/9.8tan20^circ

$$R = \frac { ( 88.99 ) ^ { 2 } } { 9.8 \tan 20 ^ { \circ } }$$

Solve for R

$$R = \frac{1979805025000000000000}{891727073952195733} = 2220\frac{1.709208261255808 \times 10^{17}}{8.917270739521957 \times 10^{17}} \approx 2220.191673923$$

Steps for Solving Linear Equation
