Answer:
4
Step-by-step explanation:
A simple matter of using Pythagoras. The hypotenuse is the ladder, and one of the legs is the wall, and we have to figure out the value of the other leg.
The Pythagorean formuda is (hypotenuse = a): a² + b² = c² (b and c are the other sides)
applying the values: a = 5 and b or c is 3 (I'll put b = 3)
5² = 3² + c²
25 = 9 + c²
25 - 9 = c²
16 = c²
√16 = c
4 = c
c = 4
Answer:

Step-by-step explanation:
According to the Alternate Interior angles theorem, the bottom left angle and the upper right angle have the same measure. Because they were formed from a pair of parallel lines crossed by a transversal one.
So, algebraically:

Answer: The cost for 42kg is $210
Step-by-step explanation:
375/75=$5 for 1kg
$5*42=$210
Answer:
See step by step
Step-by-step explanation:
For A. use any two factors that multiply to 100 that isn't 25 and 4.
For b Use one obtuse angle (angle over 90 degree) and two acute angles. Make sure they add up to 180.
For c Use any two values that add up to 52 since they didnt establish y as the midpoint.
For d. measure of angle 1 is 45 and measure of angle 2 is 45 degrees
