Answer:
Step-by-step explanation:
Evaluate the Pythagorean Theorem for the triangle.
a² + b² = c²
5² + x² = 10²
25 + x² = 100
Subtract 25 from both sides.
x² = 75
Square root.
x = sqrt(75)
Expand the radical.
x = 5*sqrt(3)
Evaluate the expression 3÷1 1/5+1/2

Answer:
35ab = 48
Step-by-step explanation:
given
5a = 6 ( divide both sides by 5 )
a =
and
7b = 8 ( divide both sides by 7 )
b =
substitute these values for a and b into the expression and simplify
35ab
= 35 × ×
( divide 35 and 5 by 5 )
= 7 × 6 ×
= 42 × ( divide 42 and 7 by 7 )
= 6 × 8
= 48
