Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
You can type that equation into a grphing calculator and get the table for from there or you can use desmos graphing calculator site and type in your equation to the column then hit the little settings icon and choose convert to table !!!
-2x+14y=148*3x+5y=256
(-2x+14y)/148=3x+5y=256/148
(-x+y)37/7=3x+5y=64/37
37*7(x+y)/37=(3x+5y)*37=64/37*37
7(x+y)=111x+185y=64
7x-111x=-7y-185y+64
104x=191y+64
x=191y+64/104
