Answer:
3
Step-by-step explanation:
It is a well known trick that when you add together the digits of a number, if they are a multiple of 3 then the number is divisible by 3. Let's go through the options and check them:
7+5+7+0=19 not a multiple of 3
7+5+7+1=20 not a multiple of 3
7+5+7+2=21 multiple of 3
7+5+7+3=22 not a multiple of 3
7+5+7+4=23 not a multiple of 3
7+5+7+5=24 multiple of 3
7+5+7+6=25 not a multiple of 3
7+5+7+7=26 not a multiple of 3
7+5+7+8=27 multiple of 3
7+5+7+9=28 not a multiple of 3
As you can see, only 3 of these were possibilities that satisified the conditions. Hope this helps!
Answer:
55R^3
Step-by-step explanation:
V= L X H X D
V= 4 X 5.5 X 2.5
V=55
Sin 39 = 8.9 / RT
RT = 8.9 / sin 39 = 14.14
cos 54 = RS / 14.14
RS = 14.14 * cos 54 = 8.3 cm Answer
52 °
add up 38+90
128
180-128= 52 and there’s your answer
