Sine theorem:
a/sin A=b/sin B=c/sin C

Data:
A=33º
a=19
b=14

19/ sin 33º=14 / sin B
sin B=(sin 33º *14) / 19
sin B=0.41312...;
B=arcsin 0.41312...=23.66º

A+B+C=180º
33º+23.66º+C=180º
C=180º-33º-23.66º
C=123.34º

a/Sin A=c/sin C
19 / sin 33º=c / sin 123.34º
c=(19 * sin 123.34º) / sin 33º
c=29.14

Answer: a=19; b=14, c=29.14; A=33º; B=23.66º; C=123.34º

1. If x = -3 , evaluate : 2x + x + 2x + 5
AVprozaik [17]

Answer:

1. -10

2.x=8

3. x= 2

Step-by-step explanation:

1. x = 3, 2x+x+2x+5

=2(-3)+(-3)+2(-3)+5

= -6 +(-3)+(-6)+5

= -6 -3 -6 +5 Next you have to use BODMAS rule so first addition

= -6 -3 -1

= -9-1

= -10

2. 2(2x+1)+x=x+2x+18

=4x+2+x=3x+18 then collect like terms:

=4x+x+2=3x+18

=5x+2=3x+18

=5x+2-2=3x+18-2

=5x=3x+16

=5x-3x=3x-3x+16

= 2x=16

2x/2=16/2

x=8

3.2x+x+2x=10+x

=6x=10+x

=6x-x=10+x-x

=5x=10

=5x/5=10/5

x=2

If its helpful ❤❤❤
