The entire expression represents the total cost of the pants and shirts that Chris bought.
25p + 18(p + 4) ....let me break this down for u...
p = number of pants bought
25p is telling us the pants cost $ 25 a piece
p + 4 is telling us the number of shirts bought...4 more shirts then pants
18(p + 4) is telling us that each shirt bought costs $ 18
Given:
A figure of a triangle.
To find:
The measure of angle A.
Solution:
Label the points in the figure as shown below.
In the below figure,
(Vertically opposite angles)
(Congregant angles)
Using exterior angle theorem in triangle ABC, we get
Isolate the variable term x.
Now, the measure of angle A is:
Therefore, the correct option is B.
sin(x) = ⁴/₅
sin⁻¹[sin(x)] = sin⁻¹(⁴/₅)
x ≈ 53.13
cos(90 - x) = cos(90)cos(x) + sin(90)sin(x)
cos(90 - 53.13) = cos(90)cos(53.13) + sin(90)sin(53.13)
cos(36.87) = 0cos(53.13) + sin(53.13)
cos(36.87) = sin(53.13)
cos(36.87) = cos(90 - 53.13)
cos(36.87) = cos(36.87)
A digit in its 10 thousandths place is 10 times more than a digit in its thousandths place.
You subtract the second number from the first number.
So 547.25 - 327.875
And you should get the answer 219.375
