Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°

ANSWER
The required angle is

EXPLANATION
Let the angle whose sine is

be

Then

We take the inverse sign of both sides to obtain,

We use our scientific calculator to evaluate and obtain,
Answer:
4,296
Step-by-step explanation:
because 4 thousands = 4,000, 9 hundreds = 900, 2 tens = 20 and 6 ones= 6, 400 + 900 + 20 + 6 = 4,920
Answer:
A) 40
Step-by-step explanation:
The sum of the interior angles of a regular polygon is:

For a hexagon, we put n=6

Let x be the 6th interior angle, then



The largest interior angle is 140°
Therefore the least exterior angle will be:

The correct choice is A
