Answer:
.
Step-by-step explanation:
Let x represent the number.
We have been given a sentence. We are supposed to translate our given sentence into an inequality.
We are told that the number is at-least 90. This means that our required number is greater than on equal to 90.
We can represent this information in an inequality as:
Therefore, our required inequality would be .

Step-by-step explanation:
Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.
To add (or subtract) two matrices, they must be the same size.
(m x n) + (m x n) = (m x n)
m x n means a matrix has m rows and n columns. Dimensions are always named in that order: rows, then columns.

x = 35
C = 18.92
A = 71.07
Step-by-step explanation:
x)
Use the Pythagorean theorem to find the unknown side.
For Angle C
The angle C can be found using the inverse sine function.
C=arcsin(opp/hyp)
C=arcsin(12/37)
C=18.92
For Angle A
The sum of all the angles in a triangle is 180 degrees.
A + 90 + 18.92 = 180
A = 71.07
