Question

Find the value of sin^2 30°+cos^2 60°+tan^2 45º​

Answer 1

Answer:

sin^2 30°+cos^2 60°+tan^2 45°

=(1/2)^2+(1/2)^2+(1)^2

=1/4+1/4+1

=1/4+1/4+4/4

=(1+1+4)/4

=6/4

=3/2

=1 1/2

Answer 2

Answer:

$\sin {}^{2} 30 {}^{0} + \cos {}^{2} 60 {}^{0} + \tan {}^{2} \: 45 {}^{0}$

$( \frac{1}{2} ) {}^{2} + ( \frac{1}{2} ) {}^{2} + (1)$

$\frac{1}{4} + \frac{1}{4} + 1$

$\frac{1}{4} + \frac{1}{4} + \frac{4}{4}$

$\frac{(1 + 1 + 4}{4}$

$\frac{6}{4}$

$\frac{3}{2}$

$\frac{11}{2}$
