Answer: I say the answer is 20 years old, 30 years old
Step-by-step explanation: If rachel is 10 years old than her sister in six years from now, the sum of their ages will be 40. So rachel is 10 years older than her sister so the younger sister has to be 20 years old and and rachel is 30 years old.
<h3>1)x=180°−(50°+60°) x = 180 ° - ( 50 ° + 60 ° ) =180°−110°=70°</h3>
<h3>2)x=180°−(30°+90°) Since it is a right angle so the third angle is a right angle. ...</h3>
<h3>3)x=180°−(30°+110°) x = 180 ° - ( 30 ° + 110 ° ) =180°−140°=40°.</h3>
<h3>4)Here; 50°+2x=180° Or, 2x=180°−50°=130° ...</h3>
<h3>5)This is an equilateral triangle. ...</h3>
<h3>6)This is a right angled triangle.</h3>

The Pythagorean theorem is: a²+b²=c², and "c" will always be the hypotenuse or the longest side of the triangle.
In order to find MN you can make a triangle, and then you can find the lengths of the other sides(a and b).
You should get a = 4 and b = 6. Next you plug these numbers into the equation.
(4)² + (6)² = c²
16 + 36 = c²
52 = c²
√52 = c
