Solve tan63^circ=15/b

$$\tan 63 ^ { \circ } = \frac { 15 } { b }$$

Solve for b

$$b = \frac{9375000000000000}{1226631565940719} = 7\frac{788579038414967}{1226631565940719} \approx 7.642881742$$

Steps for Solving Linear Equation

Evaluate trigonometric functions in the problem

$$1.9626105055051504 = \frac{15}{b}$$

Variable b cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by b.

$$1.9626105055051504b=15$$

Divide both sides by 1.9626105055051504.

$$b=\frac{15}{1.9626105055051504}$$

Expand \frac{15}{1.9626105055051504} by multiplying both numerator and the denominator by 10000000000000000.

$$b=\frac{150000000000000000}{19626105055051504}$$

Reduce the fraction \frac{150000000000000000}{19626105055051504} to lowest terms by extracting and canceling out 16.

$$b=\frac{9375000000000000}{1226631565940719}$$
