Hello there.
What is the height of the second rectangle?
12.
Answer:
The above triangle is an isosceles triangle....
Reason
As we can see AB and DE are parallel to each other
As angle ABC is 80 degree
Therefore BCE is too 80 degree (as they both are alternate to each others)
Hence angle DCB is a 50 degree because in the straight DCE we have angle BCE as <u>80 </u><u>degree</u><u> </u>and Angle ACD as <u>50 degree</u>
Since a straight line has <u>180 degree</u> therefore the remaining angle ACB is 50 degree(180-80-50)
Now in triangle BAC. Angle C is 50 degree and Angle B is 80 degree, since the total angle of a triangle is 180 degree therefore A is 50 degree that is angle BAC is 50 degree(180-50-80) .
Hence here we see that two opposite sides have same angle that is the reason its a ISOSCELES triangle

THANK YOU
Add all the beads together and put it over the number of blue beads.
so since there are 150 beads, the denominator is 150. and the amount of blue beads is 50 so that's the numerator.
50/150 now simplify, divide the numerator and denominator by 50 that equals
1/3
so the probability of getting a blue bead is 1/3
