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 :-
Answer:
485.42
Step-by-step explanation:
multiply by using` long multiplication
Answer:
Step-by-step explanation:
Substitute with x and y with 3:-
First, Multiply -1 and 3 = -3
Subtract 7 from -3 = -10
Multiply 2 and -10 = -20
