Answer:
No, it is <em>not</em> a right triangle.
Step-by-step explanation:
We know that there are <em>2 legs </em>and <em>1 hypotenuse</em>. The <em>hypotenuse is 76</em> because it is the<em> largest number</em>. And the two <em>legs are 73 and 26</em>. Now to find if it is a right triangle we will take <em>73 and multiply it by itself</em>, which is <em>5,329</em>. Now we will do the same with 26 and we get <em>676.</em> Then we <em>add 676 to 5,329</em> and we get <em>6,005</em>. Because we are trying to find the hypotenuse, we have to find what number <em>when squared</em> makes<em> 6,005</em>. Since <em>76 x 76 = 5,776</em> it is<em> not a right triangle. </em>
Here is an image of the triangle:
Answer:
ASA
Step-by-step explanation:
The right triangle cannot be A$S or AAA, SSA is incorrect.
9 and 4 is the answer for the 3rd and 4th one
You just count the number of squares on the side, and you Pythagorean Theorem for the hypotenuse.
9 + 12 + (square root of 81 +144)
9 + 12 + 15
It’s 36
Three times the 1st number plus the 2nd number plus twice the 3rd is 5 is the same as 3x+y+2z=5. If three times the 2nd number is subtracted from the sum of the 1st and three times the 3rd number, the result is 2 is just x+3z-3y=2. And if the 3rd number is subtracted from two times the 1st number and three times the 2nd, giving a result of 1 means 2x+3y-z=1. Then you use substition on these equations to get a equation where one variable equals 2 others, like using the first to get y=5-2z-3x and then this can be substituted into the other two to get x+3z-3(5-2z-3x)=2 and 2x+3(5-2z-3x)-z=1 we can then simplify and subtract the equations. After simplification we have 10x+9z=17 and 7z+7x=16 which can be turned into 70x+63z=119 and 70x+70z=160 which can be then subtracted to get that 7z=41 and z=41/7. Now we backtrack to a two variable equation like 7z+7x=16 and plug in to find x. So after plugging in we get 41+7x=16 and 7x=-25 so x=-25/7. Now we choose a 3 variable equation and plug in. So taking y=5-2z-3x we plug in 41/7 for z and -25/7 for x to get y=5-82/7+75/7 and y=5-7/7 and y=4. Therefore x = -25/7 y = 4 and z = 41/7.
