Answer:
9 boxes were packed. 10 brownies were left over.
Step-by-step explanation:
127 ÷ 13 = 9 R10
13 x 9 = 10 x 9 + 3 x 9 = 90 + 27 = 117
127 - 117 = 10
Answer:
A≈576.31
Step-by-step explanation:
surface area = bh + L(s1+s2+s3)
surface area = (13*11) + 13 * (10+11+14.87)

Given:
In an isosceles triangle LMN, LM=MN.

To find:
The measure of the angles L, M and N.
Solution:
In triangle LMN,
(Given)
(Base angles of an isosceles triangle are equal)
Now,




On further simplification, we get




The value of x is 13. Using this value, we get



Similarly,



And,


Therefore, the measure of angles are
.
Step-by-step explanation:
1.


Therefore,

2.


Use the identity

We chose the negative value of the cosine because of the condition where cot y > 0. Otherwise, choosing the positive root will yield a negative cotangent value. Now that we know the sine and cosine of y, we can now solve for the tangent:

3. Recall that sec x = 1/cos x, therefore cos x = 5/6. Solving for sin x,

Solving for tan x:
