Answer: x=3 and y=5

Step-by-step explanation: 11x-6y=3, 5x-8y=-25

11x-6y+6y=3+6y

11x/11=3/11+6y/11

x=3+6y/11

5(3+6y/11)-8y(11)/11

5(6y+3)-88y/11

30y+15-88y/11

88y-30y

58y

11(15-58y)/11=11(-25)

15-58y-15=-275-15

-58y/-58=-290/-58

y=5

x=3+6(5)/11

3+30

33/11

x=3

x=3, y=5

In the triangle below, b = _____. If necessary, round your answer to two decimal places.

lara [203]

Angle B=180-(38+31.6)=110.4
by law of sin
sin B/b=sinA/A
sin(110.4)/b=sin38/25
b=25*sin(110.4)/sin(38)=38.06

Find side AB 14() 24() 33() 40()

Ahat [919]

Answer:

$AB=DC=32\ units$

$AD=BC=24\ units$

Step-by-step explanation:

we know that

In a parallelogram, opposite sides are parallel and congruent

In this problem we have a parallelogram

$DC=AB$

$AD=BC$

substitute the given values

$5x-18=2x+12$

$5x-2x=12+18$

$3x=30$

$x=10$

Find the length of side AB

$AB=2x+12$

substitute the value of x

$AB=2(10)+12=32\ units$

Find the length of side CB

$BC=3x-6$

substitute the value of x

$BC=3(10)-6=24\ units$

therefore

$AB=DC=32\ units$

$AD=BC=24\ units$
