Answer:
c = 9.43 cm
Step-by-step explanation:
Here, we want to get the measure of the missing side
By the use of Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
we have this as follows;
The side c represents the hypotenuse as it faces the hypotenuse
We have this as;
c^2 = 5^2 + 8^2
c^2 = 25 + 64
c^2 = 89
c = √89
c = 9.43 cm
Answer:
y=26, x=-3
Step-by-step explanation:
3x+y=17
3x+y-y=17-y
3x=17-y
Divide both sides by 3
Simplify
\frac{17-y}{3}+2y=49
\frac{17-y}{3}\cdot \:3+2y\cdot \:3=49\cdot \:3
17-y+6y=147
17+5y=147
17+5y-17=147-17
5y=130
\frac{5y}{5}=\frac{130}{5}
y=26
x=\frac{17-26}{3}
x=-3
