Answer:
This is call an obtuse angle
Step-by-step explanation:
because 130+70 is greater than 90
To find the hypotenuse, simply use the pythagorean theorem. A^2+B^2=C^2
You know the two legs 7 and 8, so plug it in for A and B
7^2+8^2=C^2
49+64=C^2
113=C^2
C= approximately 10.63
Answer:
x^2-2x+1
this factors out to (x-1)(x-)
both of those are equal to x=1
1st number: 0
2nd number: 17
Answer
Step-by-step explanation:
3x+2y=34 x is the first number, y is the second.
1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.
x+4y=68 solve for x.
x=68-4y add this into the first equation to solve for variable y.
3(68-4y)+2y=34 solve for y.
204-10y=34
-10y= -170
y=17
now to solve for x
x= 68-4(17)
x= 0
Step-by-step explanation:
a) 2z+3z+4z=180
9z=180
z=20
So,three angles are 40,60 and 80
b) (y+30)+(2y+80)+(y+10)=180
y+30+2y+80+y+10=180
4y+120=180
4y=60
y=15
Three angles are 45,110,25
