i need help in geometry?

Question

46). m m

please is do tomorrow

Answer 1

Complementary angles are two angles who add up to be 90.
3x-7+11x-1=90
14x-8=90
14x+98
x=7
Plug the 7 into the expression for A.
3(7)-7=A
A=14
11(y)-1 = B
B=76
Check: 14 + 76 = 90 YES
Good to go.

Answer 2

47).
If you meant to type m angle A = 3/4 x - 13°, then here is the solution.

m angle A + m angle B = 3/4 x - 13° + 3 x - 17° = 90°
15/4 x - 30° = 90°
15/4 x = 90° + 30°
15/4 x = 120°
15 x = 4 (120°)
15 x = 480°
x = 480°/15
x = 32°

m angle A = 3/4 (32°) - 13° = 24° - 13° = 11°
m angle B = 3 (32°) - 17° = 96° - 17° = 79°

m angle A + m angle B = 11° + 79° = 90°

So, this solution works.

Answer 3

i don't know which goes with which but here is the solution.

Complematary angles add up to 90 degrees.


replace
Never mind: i found the pair

3x - 7 + 11x - 1 = 90
14x - 8 = 90
14x = 98
x = 7


do the samething for number 47.

Hope this helps

Answer 4

Because Complementary angles add up to 90, you know that
46) m
Substitute m (3x-7) + (11x-1) = 90 Substitute
14x - 8 = 90 Add the x's and #s
14x = 98 Add 8 to both sides
x = 7 Divide both sides by 14

Now you know m So, m
m So, m
47) m
--I think you typed something wrong.

Answer 5

46. 3x-7+11x-1=90
14x-8=90
14x=98
x=7
m m 47. 3/4-13+3x-17=90
Ummm...did you type something incorrectly?

Good luck with your assignment.
