Answer:
B
Step-by-step explanation:
You are given two sides and the included angle, so you need to use the law of cosines.
c² = a² + b² - 2ab cos C
c² = 12² + 13² - 2(12)(13)cos 134°
c² = 313 - 312(-0.6947)
c² = 529.733
c = 23.016
Now use the law of sines.
c/sin C = a/sin A
23.016/sin 134° = 12/sin A
sin A = 12 × sin 134° / 23.016
sin A = 0.37504
A = 22.03°
B = 180° - 134° - 22.03°
B = 23.97°
m<A = 22°; m<B = 24°; c = 23 km

$51
Step-by-step explanation:
do 13*3 because of the 2 kids and the adult then add 12 because of the snacks
hope this helps
No
It is not proportional, because when x = 0, y does not equal 0.
when x = 0, y = -4. Therefore, it doesnt pass through the origin.
Its asking you to draw rectangles with sides that equal 30 cm for example
36/15 = 8/a
multiply a .. on both sides
a×36/15= 8
multiply 36/15 reciprical on both sides
a= 8 × 15/36
a= 120/36
a= 3.33
