So, 34 divided by 8 is 4.25 so thats the missing side length. It gives you the other one which is 8. So 4.25 times 8 would be your area. 4.25*8=34. your answer is 34 feet squared.
Answer: x=13
Step 1: Define isosceles triangle
In an isosceles triangle, two sides and angles are equal. The equal sides will be the legs.
Step 2: Write an equation
To write an equation we must first consider the information discussed in step 1. Since we know that the legs will be equal, we will add that to the equation twice. The base and legs will be on one side of the equation, and the perimeter will be on the other. Now we can write the equation!
x+3x-7+3x-7=77
Step 3: Combine like terms
Like terms are terms that share the same variable, or lack of. Let’s add/subtract these now.
x+3x-7+3x-7=77
7x-14=77
Step 4: Solve for x
Let’s do the last part of the equation and solve for x, our final answer.
*Rewrite equation*
7x-14=77
*Add 14 to both sides*
7x=91
*Divide 7 on both sides*
x=13
This is your answer. Hope this helps! Comment below for more questions.
centre of the circle =Midpoint of the diameter
centre of the circle=
radius of the circle=
equation of the circle: (x+2)²+(y-3)² = 40
ie.. x²+4x+4+ y²- 6y+ 9=40
ie... x²+y²+4x-6y-27=0
this is the answer......
