Answer 1

✨Answer:

<a = 60 degree and <c = 30 degree.

✨Step-by-step explanation:

IN TRIANGLE ABC :-

<b = 90

Ab = 3 cm and ac = 6 cm.

Sin <c = p/h

Sin <c = ab/ac

Sin <c = 3/6 = 1/2.

Now sin 30 = 1/2.

➡️ Therefore, <c = 30 degrees.

In triangle abc.

<b = 90, <c = 30

<a + <b + <c = 180 degree

(sum of all angles of triangle is 180 degree)

<a + 90 + 30 = 180

<a + 120 = 180

<a = 180 - 120

➡️ <a = 60 degree
