12 = 60 degrees.
The "C" pattern means that whatever is on the top/bottom corner will be equal to the opposite one.
Answer:
y = 90 -5/2 x
Step-by-step explanation:
The angle on the left equals x+3x+x = 5x
The angle on the right equals 2y
The two angles are same side interior angles which are supplementary because the lines are parallel
5x+2y = 180
Solving for y
2y = 180-5x
Divide by 2
2y/2 = 180/2 -5x/2
y = 90 -5/2 x
Answer:
Step-by-step explanation:
We can use the following trigonometrical identity:
(1)
Where , are angles, measured in sexagesimal degrees.
If we know that and , then the value of the given function is:
Answer:
MN=25
Step-by-step explanation:
mn=(ab+cd)/2 --> mn=(40+10)/2 --> mn=50/2 --> mn =25
(this is half an answer and this is what i could get)
No; try multiplying 0.25 w different numbers
1*.25= .25
2*.25= .5
3*.25= .75
