From Trignometry chapter...
10'th​

Answer 1

Answer:

right answer is 1

Step-by-step explanation:

sin60°×cos30°+sin30°×cos60°

=√3/2×√3/2+1/2×1/2

=(√3/2)^2+(1/2)^2

=3/4+1/4

=1

Answer 2

Answer:

HERE VALUES ARE SIN 60=√3/2, COS 30=√3/2

sin 30= 1/2, cos 60=1/2

SO HERE BY PUTTING VALUES OF SIN AND COS

√3/2 × √3/2 + 1/2 × 1/2

THUS 3/4 + 1/4

THUS 4/4

THUS UR ANS. IS 1
