How many triangles can be constructed with three angles, each measuring 64°? 10 points

NONE

Step-by-step explanation:

The answer is none. This is because angles in a triangle must add up to 180°, so if you have three angles that are 64° the total would be 192°. I hope this helps!

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

if the probability is 1/12, 75 people will receive a $25 gift card
