Answer:
135. isosceles triangles have two equal sides/angles. <CBD is 135, from adding 70 and 65.
Answer:
135 degrees
Step-by-step explanation:
Angle CBD is the sum of angle ABC and angle ABD, so we find these first An Isosceles triangle has 2 equal sides and 2 equal angles Isosceles triangle theorem tells us that the 2 equal angles are respectively opposite the equal sides Since triangle ABC has sides AB=AC, then angle ACB = angle ABC So knowing that angles of triangle add up to 180, then Now we do the next triangle to get ABD Since triangle ABD has sides AB=BD, then angle BDA = angle BAD So knowing that angles of triangle add up to 180, then Now we said, angle CBD is the sum of angle ABC and angle ABD, so

Step-by-step explanation:
The chance of getting tile number 5 from the first bag is 1/6 as it is for all other tiles in the same bag. The chance of getting an odd tile from the second bag is 3/6 as it is for getting an even tile. By multiplying the two, we get a total probability of 1/12.
1. 3/4 x 36 = 27 2. 30 x 13/10 = 39 3. 9/8 x 32 = 36 4. 1/2 x 60 = 30 5. 3/4 x 60 = 45 6. 3/10 x 1000 = 300 7. 4/5 x 100 = 80 ~Good Luck~!
X(3 + x) = 3x + x^ Distribute the x: 3x + x^ = 3x + x^ Since they’re the same..... x = all real numbers
