Please solve above question (I will mark as brainlist) Step by Step explanation

Answer 1

HOPE IT HELPS

Step-by-step explanation:

in triangle ABC :-

first find angle C .....

angle A + angle B + angle C = 180°

= 30° + 90° + angle C = 180°

= angle C = 180 - 120

= 60°

Now,

we have to find sin A for which we need the side AC

so , angle A = 30°

we can say that angle A as sin30°

sk, sin30° = 1/2 ......(1) and sin A = BC/AC.....(2)..

SOLVING EQN.:-

we get ratios :-

1/2 = BC/ 6 cm

= BC = 6 × 2

12 cm

now for cos theta we need base and hypotenuse pf angle C ( as per question) which we already have the values....

so

sin A + cos C

= BC/AC + BC/AC

= 6/12 + 6/12

= 1/2 + 1/2

= 1 ( ans)
