You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²) b = 9.16
With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10
75+22= 97 estimated= 100
therefore , estimate from there.
9 is greater and 7 is greater so you’d go up. 100 would be the answer i think. but if you need help with the 75 estimated and 22 estimated it’ll be ...
75 = estimated =80
22 = estimated =20
80+20= 100.
100 is the answer.
Answer:
![2+2-1-1+6=x : x = 8](https://tex.z-dn.net/?f=2%2B2-1-1%2B6%3Dx%20%3A%20x%20%3D%208)
Step-by-step explanation:
![2+2-1-1+6=x\\](https://tex.z-dn.net/?f=2%2B2-1-1%2B6%3Dx%5C%5C)
Switch sides:
![x=2+2-1-1+6](https://tex.z-dn.net/?f=x%3D2%2B2-1-1%2B6)
Add/Subtract the numbers: ![2+2-1-1+6=8](https://tex.z-dn.net/?f=2%2B2-1-1%2B6%3D8)
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
Hope I helped, if so may I get brainliest and a thanks?
Thank you, have a good day! =)
Answer:
Equation : x + 1 + 3x = 7
Miles Lissette biked : 3/2 miles
Step-by-step explanation:
<em>Step 1: Determine the total number of miles biked.</em>
From my understanding. 7 miles is the total number of miles biked by both.
<em>Step 2: Assume the values</em>
Miles Lissette biked = x
Miles Shane biked = 1 + 3x
<em>Step 3: Add miles biked by Lissette and Shane which will be equal to total miles. </em>
Equation for miles Lissette biked: x + 1 + 3x = 7
4x + 1 = 7
x = 6/4
<em>Step 4: Simplify</em>
x = 6/4
x = 3/2
Therefore, the equation for miles Lissette biked is x + 1 + 3x = 7 and Lissete biked for 3/2 miles.
