Answers:</h3><h3>
x = 12</h3><h3>
Angle B = 45 degrees</h3>
===========================================================
Explanation:
Angles A and B are alternate exterior angles.
Due to the parallel lines, alternate exterior angles are congruent
A = B
5x-15 = 2x+21
5x-2x = 21+15
3x = 36
x = 36/3
x = 12
Use this x value to find the measure of angle B
angle B = 2x+21
angle B = 2*12+21
angle B = 24+21
angle B = 45 degrees
As a check,
angle A = 5x-15
angle A = 5*12+15
angle A = 60-15
angle A = 45 degrees
Since A and B are both 45 degrees, this confirms the correct x value

Answer:
square root of 7
Step-by-step explanation:
Each right angle triangle has 3 sides known as the opposite, adjacent and hypotenuse sides. The relationship between these 3 sides is as defined by pythagoras theorem which states that
a² + b² = c²
where a and b are the lengths of the opposite and adjacent sides (in no particular order) and c is the length of the hypotenuse side.
Given that the leg of a right triangle is 3 units and the hypotenuse is 4 units, it means that
a² + 3² = 4
where a is the length in units, of the other leg of the triangle
a² = 4² - 3
a² = 16 - 9
= 7
a = √7
