Answer:
x = sqrt(39)
Step-by-step explanation:
Let y = common side of the two triangles.
Upper right triangle:
6^2 + y^2 = 10^2
y^2 = 100 - 36
y^2 = 64
y = 8
Lower left triangle:
5^2 + x^2 = 8^2
x^2 = 64 - 25
x^2 = 39
x = sqrt(39)
Answer:
1.95 kilograms
Step-by-step explanation:
7.8/4 = 1.95
Answer:
18 + √3
Step-by-step explanation:
The product of a surd and its conjugate gives a rational number. Hence;
(18 - √3) (18 + √3)
=324 + 18√3 - 18√3 - 3
=321
A rational number does not contain any surd, hence the answer.
17+3f=14
3f= 14-17
3f/3= -3/3
f=-1 .
