To solve this problem you first need to establish what it is you are looking for.. if you knew the grandson age then you could find your son and you. So that is what we need to find and since we don't know it, we will call it x.
Grandson = x
Son = 7x
You = 12x
Then it says the sum of the 3 is 100.... x + 7x + 12x = 100 then solve and find that x = 5. So to determine your age, just put 5 in for x and you get 60... dang your old ha
10.23 feet is the answer because when you line up the decimals and add, its 10.23
Answer:
scalene
Step-by-step explanation:
step 1
Find the value of y
we know that
The sum of the interior angles in a triangle must be equal to 180 degrees
In this problem
m∠A+m∠B+m∠C=180°
substitute the given values
![90\°+(y+40)\°+(3y-10)\°=180\°](https://tex.z-dn.net/?f=90%5C%C2%B0%2B%28y%2B40%29%5C%C2%B0%2B%283y-10%29%5C%C2%B0%3D180%5C%C2%B0)
Solve for y
![4y+120=180](https://tex.z-dn.net/?f=4y%2B120%3D180)
![4y=180-120](https://tex.z-dn.net/?f=4y%3D180-120)
![4y=60](https://tex.z-dn.net/?f=4y%3D60)
![y=15](https://tex.z-dn.net/?f=y%3D15)
step 2
<em>Find the measure of angle B</em>
m∠B=(y+40)°
substitute the value of y
m∠B=(15+40)=55°
step 3
<em>Find the measure of angle C</em>
m∠C=(3y-10)°
substitute the value of y
m∠C=(3(15)-10)=35°
The three interior angles are different
so
The three sides of the ABC triangle will also be different
therefore
The right triangle ABC is scalene
