Answer:

Figure 1: x = 120°

Figure 2: x = 54°

Figure 3: x = 64°

Step-by-step explanation:

Every triangles interior angles will add up to 180°

Figure 1: 30 + 30 + x = 180

60 + x = 180

x = 120

Figure 2: 104 + 22 + x = 180

126 + x = 180

x = 54

Figure 3:

part 1: 154 + z = 180

z = 26

part 2: 90 + 26 + x = 180

116 + x = 180

x = 64

Answer:

1. 120

2. 54

3. 64

Step-by-step explanation:

30 + 30 = 60

180-60 = 120

104 + 22 = 126

180 - 126 = 54

180 - 154 = 26

26 + 90 = 116

180 - 116 = 64

Answer:

So, The answer would be 1=k

Step-by-step explanation:

My step is to make a T-chart, as u make it put X on one side and Y on the other

So what i did was i put 0 for both of them because it had start at 0

then i followed the line to the dot as i did that It has 6,6 so then i figured out what multiply all those number and the answer was 1=k

And another way you could do it was to make 6,6 and fraction like 6/6 then divde them both and get 1=k

So you would put the answer as 1

thats it Answer-1

Find the value of x round to the nearest tenth

Leto [7]

Answer:

58.6

Step-by-step explanation:

Use the formula $c=\sqrt{a^{2}+b^{2}$

solving for x (b)

$b=\sqrt{c^{2}-a^{2}$ = $\sqrt{61^{2}-17^{2}$ ≈58.58327

and 58.58327 rounds to 58.6
