Answer:
x=50
Step-by-step explanation:
4x+50+110=360
4x=360-160
4x=200
x=200/4=50
Answer:x=8 and y=2
Step-by-step explanation:
To find 2x-4y=8 and 3x+6y=36
Solve simultaneously
Using elimination method
6x-12y=24
6x+12y=72
To eliminate x
-24y=-48
Divide through by -24
y=2
To get x
Substitute for y in equation 1
2x-4(2)=8
2x=8+8
2x=16
Divide through by x
x=8
Answer:
Step-by-step explanation:
Base of the isosceles triangle = 4
Perpendicular of the triangle = 3
In an isosceles triangle , a perpendicular bisects a base equally. So, here the isosceles triangle consist of 2 right angled triangles.
In that right angled triangles,
Base = 4/2 = 2 (∵ A perpendicular divides a base into 2 equal parts. )
Perpendicular = 3
Hypotenuse = x
So , according to Pythagorean Theorem ,
Using all the values above into the formula gives :-
