Answer 91 degrees
360-93-86=182/2=91
***** i meant 1/24, lol oops
Answer:
Option c) is correct.
That is x-5y=12 and 3x+2y=-15 are the system of linear equations satisfies the point (-3,3) so this is the solution.
Step-by-step explanation:
To verify that which system of linear equations having the solution (-3,-3)
Let
and
To solve it we have to use elimination method
First multiply the equation(1) into 3 we get
Now subtracting the equations (2)and (3) the signs may vary in the second equation we get
________________
_______________
Now substitue the value y=-3 in equation (1) we get
Therefore x=-3
Therefore the solution is (-3,-3)
Therefore Option c) is correct.
That is x-5y=12 and 3x+2y=-15 are the system of linear equations satisfies the point (-3,3) so the solution is (-3,-3).
Answer:
x=24
Step-by-step explanation:
Use Pythagorean Theorem to solve for x.
7^2+x^2=25^2
49+x^2=625
-49 - 49
x^2=576
sqrt sqrt
x=24
