Answer:
60 degree
Step-by-step explanation:
They are complementary angles which means they must add up to 90.
As WOX is 30 degree then
90-30=60.
yoz would also be 60 degrees because wov and yoz are equal
There are 4 9's in a deck.
The probability would be 4 / 52 = 0.07692
Rounded to the nearest hundredth = 0.08
Answer:
a = -4.
Step-by-step explanation:
If the are perpendicular then the slope of one graph will be - 1 / slope of the other.
Convert each equation to slope-intercept form:
x + 2y + 3 = 0
2y = = -x - 3
y = (-1/2)x - 3/2 (Slope/intercept form)
So the slope of the line perpendicular to this will be - 1 / (-1/2) = 2.
Consider the other line:
ax + 2y + 3 = 0
2y = -ax - 3
y = (-a/2) x - 3/2 (Slope/intercept form)
So the slope for this line - a/2 and it equals 2.
-a/2 = 2
-a = 2*2 = 4
a = -4 (answer).
All triangles add up to 180 degrees. Since sines can't be a negative, you need to add -130 to 180. The answer to this question would be sine 50 degrees.
