We have that
y=sin O
for O=270°
find the value of sin O

we know that
270 degrees --------> convert to radians-------> is equal to 3pi/2

using a graph tool
see the attached figure

the value of sin O for O=3pi/2  is -1

the answer is
-1

Refer to the image, the 270 degrees corresponds to 3/2 pi. 

Based on the graph, the value of sin(270) is -1.

So, the answer is -1.

In the diagram, what is the value of x?
Ghella [55]

Answer:

x = 162

Step-by-step explanation:

the sum of the interior angles of a quadrilateral = 360°

sum the interior angles of the quadrilateral and equate to 360

90 + 60 + x + 48 = 360 , that is

198 + x = 360 ( subtract 198 from both sides )

x = 162
