Answer:
C: a reflection across the y axis rotated 180 degrees
Step-by-step explanation:
The y axis is a vertical line, the same like that the trapezoid is flipped across
The trapezoid is rotated 180 degrees across the y axis
Answer:
√2/2
Step-by-step explanation:
If sinP = √2/2,
Rationalize;
√2/2
= √2/2,*√2/√2
√4/2√2
= 2/2√2
= 1/√2
Hence sinP = 1/√2
Take sin inverse of both sies
arcsinP = arcsin1/√2
P = 45 degrees
cos P = Cos 45
= 1/√2
= 1/√2 * √2/√2
= √2/2
Hence the value of cosP is √2/2
Answer:
X-intercept = -3 and y-intercept = 6
Step-by-step explanation:
We can start off by isolating the y term. To do that, we must add 2y to both sides to get
Now, we must add 12 to both sides and the y term will be all alone on the right side:
Now, to have only y on the right side, we must divide by 2 to get:
In slope-intercept form, b is the y-intercept, and 'b' in this equation is 6. We have our y-intercept.
To find our x-intercept, y must be equal to zero. We can plug in that value for y and solve for x:
We can start off by subtracting 6 from both sides to get:
We can then divide both sides to get when y is equal to 0. Thus, we have our x-intercept.
2 and 1/4 = 9/4
4 and 1/12 = 49/12
3 and 2/3 = 11/3
Perimeter = 9/4 + 49/12 + 11/3
= 27/12 + 49/12 + 44/3
= 120/12
= 10inches
M∠3 + m∠4 = 180° ( RIGHT)
m∠2 + m∠4 + m∠6 = 180° ( RIGHT)
m∠2 + m∠4 = m∠5 ( RIGHT)
m∠1 + m∠2 = 90° (WRONG)
m∠4 + m∠6 = m∠2 (WRONG)
m∠2 + m∠6 = m∠5 (WRONG)
