Answer:
(-2,3)
Step-by-step explanation:
You can see that the purple is the new triangle. So look at the coordinate of the D. You can see that it is plotted at (-2, 3)
I’m to lazy to figure out this question
Answer:
B
Step-by-step explanation:
In an isosceles trapezoid any lower base angle is supplementary to any upper base angle, thus
6x + 2x + 4 = 180, that is
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22 → B
The answer is C because is n is positive and even it will only open up.
Answer:
Step-by-step explanation:
cos(x) = sin(15°)
x = arccos(sin(15°)) = 75°
