We are supposed to assume FC and AD is straight line
let's find all the angles

you already see the right angle is 90 degrees, you got that right
striaght line is 180 degrees

90+46+EF=180
136+EF=180
minus 136 both sides
EF=44
now we got another straight line
you did get that A F=46 because it is oposite

notice: AB=BC because same angle designition
so now we use
180+46+2AB=360
2AB=134
divide 2
AB=67=BC
AC=134 degrees
CAE=134+46+44=224
ABD=180 since straight line

a. 90
b. 224
c.134
d. 180

HELP!

tigry1 [53]

Answer:

$b=40.01\ units$

Step-by-step explanation:

we know that

Applying the law of sines

$\frac{b}{sin(B)}=\frac{a}{sin(A)}$

$b=\frac{a}{sin(A)}(sin(B))$

we have

$a=25\ units$

$A=32.5\°$

Find the measure of angle B

Remember that the sum of the interior angles of a triangle must be equal to 180 degrees

$A+B+C=180\°$

substitute the given values

$32.5\°+B+26.8\°=180\°$

$B=180\°-59.3\°=120.7\°$

Find the length side b

$b=\frac{a}{sin(A)}(sin(B))$

substitute the values

$b=\frac{25}{sin(32.5\°)}(sin(120.7\°))$

$b=40.01\ units$
