C is the incorrect sentence.
Answer:
x = √5
Step-by-step explanation:
The Pythagorean theorem tells you the square of the diagonal is the sum of the squares of the two sides:
(√7)² = (√2)² + x²
7 = 2 + x² . . . . . . simplify
5 = x² . . . . . . . . . subtract 2
√5 = x . . . . . . . . . take the square root
Answer:
what's the question? u did not said it
13 + 9 = 22 feet
the angle is 50 degrees
multiply 22 x tan(50) to find the height of the lamppost
22 x tan(50) = 26.21

Answer:
Part A is 3/8 of the whole
Part B is 5/8 of the whole
Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 5 = 8
Part A = 3 and Part B = 5 are numerators for each fraction.
The fractions are then:
3/8 and 5/8
Meaning:
Part A is 3/8 of the whole
Part B is 5/8 of the whole
