you are asked to draw a triangle using three of the following angles: 0°, 30°, 45°, 55°, 60°, 80°, 90°, 105°. which triangle cannot exist?
a) 30°, 60°, 90°
b) 45°, 55°, 80°
c) 30°, 45°, 105°
d) 30°, 45°, 55°

D

Step-by-step explanation:

When you add all the the angles of a triangle, they  will end up to be exactly 180 degree. When you add the three numbers A, B, and C end up with 180 degree, but D end up with 130 degree, therefore, D is the triangle that cannot exist.

Hope it helps :D

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
