10^2 + 7^2 = c^2
100 + 49 = c^2
149 = c^2
Square root of 149 = square root of c^2 ( cancels out the ^2)
C= square root of 149
1. 12.2
2. 8.9
3. 21.7
4. 13.9
The formula is a2 + b2 =c2.
You plug in the numbers and solve. C is always the hypotenuse of the triangle. You can use the legs as either a or b.
1.
10^2 + 7^2 =C^2
100 + 49 = C^2
149 = C^2
Then square root both sides to get 12.20.
2.
19 ^2 + b^2 = 21 ^2
361 + b^2 = 441
Subtract 361 from both sides
b ^2 = 80
Square root both sides
b=8.94
3.
16 ^2 + b ^2 = 27 ^2
256 + b ^2 = 729
Subtract 256 from both sides
b ^2 = 473
Square root both sides
b=21.74
4.
5.3 ^2+ 12.8 ^2 = c ^2
28.09 + 163.84 = c ^2
191.93=c ^2
Square root both sides to get
C=13.85

Answer:
It will take Amanda 3 track practices to run 29 miles.
Step-by-step explanation:
29-14=15
15/3=5
or
14+5x=29
subtract 14 from both sides
5x=15
divide both sides by 3
x=3

Draw a line from F to (0,0). If you rotate that line 90 degree counterclockwise about the origin, the coordinate of F’ will be (4,1)
You'd use tangent for this.
opposite / adjacent
tan 60* = x/14
multiply both sides by 14
tan 60* = 1.73
tan 60* (1.73 x 14) = x
24.22 = x
Your answer should be 24.22
