Calculate the value of angle A and C of ∆ ABC. Where b=1435cm, a= 782cm and B= 115.6°.​
Monica [59]

The Law of Sines says

\dfrac{\sin A}{a} = \dfrac{\sin B}{b} = \dfrac{\sin C}{c}

\sin A = \dfrac a b \sin B

A = \arcsin( \dfrac{782}{1435} \sin 115.6 ) = 29.44^\circ

We don't have to worry about the obtuse supplement because a triangle can only have one obtuse angle, and that's B.

C = 180 - 115.6 - 29.44 = 34.96^\circ

Answer: A=29.44°, C=34.96°

Answer:

C is correct

Step-by-step explanation:

Given: System of linear inequality

y

y\geq 2x+3

First we will draw the graph of system of equation and then see the correct option.

Equation 1: y

We will make the table.

 x :  -2    0     2

 y :   1     0    -1

Test Point: (0,4)

0<-2 ( False )

Shaded area away from (0,4)

Equation 2:y\geq 2x+3

We will make the table.

 x :  -2    0     2

 y :  -1     3    7

Test Point: (0,4)

4≥3 ( True )

Shaded area towards (0,4)

Please see attachment for graph.

Hence, C is common shaded area (region)
