At what angle would a carpenter cut a board to create a complementary angle if the other end was cut to 35 degrees?

45 degrees

35 degrees

60 degrees

55 degrees

55 degrees

Step-by-step explanation:

So to figure this out, you need to know what a complementary angle is. A complementary angle is a 90 degree angle.

Now you know what a complementary angle is, all you have to do is 90-35 to find the remaining angle.

90-35=55

The answer is 55 degrees

sine

step-by-step explanation:

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
