Answer:
A. 47 degrees
Step-by-step explanation:
If both sides are equivalent in length, that means that the two remaining angles are also the same. Triangles have an interior angle sum of 180 degrees, so subtract the 86 of the angle known, and divide the remaining degrees by two to find each angle.

Ok! Nice question, by the way!
11 + 11 = 4
What is the sum of the digits of 11? 1 + 1 = 2.
Now square that. You get 2^2 = 4.
12 + 12 = 9
What is the sum of the digits 12? 1 + 2 = 3.
Now square that. You get 3^2 = 9.
Now, 13 + 13 = ?
What is the sum of the digit 13? 1 + 3 = 4
Now square that. You get 4^2 = 16.
13 + 13 = 16.
Answer: No
Step-by-step explanation: If you plug in 10 for y and 2 for x, the equation becomes 10=9(2), which is 10=18.
Answer:
(i) 14 groups
(in) 15 boys per group and 16 girls per group
Step-by-step explanation:
(i) After the withdrawal of the 4 boys and 6 girls, there are 210 boys and 224 girls left. To find the greatest number of groups that can be formed with an equal number of boys in each group and an equal number of girls in each group, you need to find the GCF (Greatest Common Factor) of 210 and 224. Since 210 is 2 * 3 * 5 * 7 and 224 is 2^5 * 7 the GCF of these two numbers is what they have in common which is 2 * 7 which is <u>14</u>. Thus, 14 is the greatest number of groups that can be formed.
(in) When 14 groups are formed, there are 210/14 boys in each group and 224/14 girls in each group. That results in <u>15</u> boys per group and <u>16</u> girls per group.
Hope this helps :)
