LHS: =

(using

)
We know

so we can replace the sin²x in the LHS expression as follows

which is the RHS.
Answer:
x = 11°
Step-by-step explanation:
The parallel lines suggest we look to the relationships involving angles and transversals. The angle marked 33° and ∠CAB are alternate interior angles, hence congruent:
∠CAB = 33°
5x is the measure of the external angle opposite that internal angle and angle 2x of ΔABC, so it is equal to their sum:
5x = 2x + 33°
3x = 33° . . . . . . . . . subtract 2x
x = 11° . . . . . . . . . . . divide by 3
A square matrix has the same number of rows as columns. In computer graphics, square matrices are used for transformations. A rectangular matrix is one where the number of rows or columns may not be the same. ... Below is a 4 x 1 column matrix. A row matrix consists of a single row.
4 and 5 are two integers between 2 and 6
Answer:
angles one and two are supplementary angles and adjacent angles
Step-by-step explanation:
Definitions:
Supplementary angles: two angles that add to 180 deg
Adjacent angles: two angles that have a common side and a common vertex (corner point) and don't overlap
complementary angles: two angles that add up to 90 deg
vertical angles: two angles that are directly opposite from each other, formed by intersecting lines
