I’m pretty sure the answer is a have a good day sorry if I’m wrong
Answer:
1) 39
2) 59
3) 53
4) 38
5) 9
6) 12
7) 15
8) 11
Step-by-step explanation:
if the angles together is a right angle than you just subtract the angle that is known from 90 and you get your other angle.
1) 90 - 51 = b = 39
2) 90 - 31 = b = 59
3) 90 - 37 = b = 53
4) 90 - 52 = b = 38
5) 90 - 56 = 34
34 = 3x + 7
3x + 7 - 7 = 3x
34 - 7 = 27
3x = 27
3x / 3 = x
27 / 3 = 9
6) 90 - 48 = 42
42 = 3x + 6
3x + 6 - 6 = 3x
42 - 6 = 36
3x = 36
3x / 3 = x
36 / 3 = 12
7) 90 - 47 = 43
43 = 2x + 13
2x + 13 - 13 = 2x
43 - 13 = 30
2x = 30
2x / 2 = x
30 / 2 = 15
8) 3x + 5x + 2 = 90
8x + 2 = 90
8x + 2 - 2 = 8x
90 - 2 = 88
8x = 88
8x / 8 = x
88 / 8 = 11
You would do 4-2= 2 then 8/2 =4 .. final answer being 4
Answer: x^2+7x+10
Step-by-step explanation:
Answer:
x = 
Step-by-step explanation:
5x + 2(x + 1) = 4
5x + 2x + 2 = 4 (here we got rid of the parenthesis)
7x + 2 = 4 (here we summed both of our x values)
7x = 4 - 2 (here we took #2 to the other side of the equation)
7x = 2 (we subtracted 4 - 2)
x = 2 / 7
x =
