Answer:
The leg measures 14.14 cm
Step-by-step explanation:
The "40 - 40 - 90" special right triangle is an isosceles right triangle because two angles measures the same. (Check the picture)
The legs are the same.
The hypotenuse is:
a × √2
From the question, the length of the hypotenuse is 20 cm.
20 = a × √2
20 ÷ √2 = a
a = 10√2 ≈ 14.14 cm
5-x÷3=-7
Add 3 to both sides of the equation.
5x=3+7
Divide each term by 5 and simplify.
Divide each term in 5x=10 by 5
5x/5=10/5
Reduce the expression by cancelling the common factors.
x= 10/5
Divide 10 by 5
Answer <em>x </em>=2
Answer:
First Option (-4,-3)
Step-by-step explanation:
x+2y=-10
-y=3x+15
-4+2(-3)=-10
-10=-10
-3=3(-4)+15
-3=-3
