Answer:

75 degrees

Step-by-step explanation:

1. Find angle J.

The outside angle and angle J are supplementary, which means they add up to 180 degrees.

180 - 130 = 50.

So angle J is 50 degrees.

2. The angles in a triangle add up to 180. Add up angles J and K and subtract that from 180

50 +65 = 105

180- 105 = 75

Artemon [7]
Vcylinder-Vsphere=water


Vcylinder=hpir^2
Vsphere=(4/3)pir^3


given

cylinderradius=30 and h=100
Vcylinder=100pi30^2=100pi900=90000pi
let's leave it in terms of pi for more exactness

sphereradius=12
Vsphere=(4/3)pi12^3=2304pi


cylinder-sphere=90000pi-2304pi=87696pi
using pi=3.14
water=275365.44 cubic cm

last option is corrrect

Triangles 1 and 2 are both isosceles. They each have a 30 degree angle. Explain why these triangles don't have to be similar to
Vladimir79 [104]

Step-by-step explanation:

Triangle 1 can have 30°, 75° and 75° angles whereas Triangle 2 can have 30°, 30° and 120° angles.

Since they do not have all 3 congruent angles, they are not similar.
