Answer:
x=24cm
y=20,78cm
Step-by-step explanation:
sen(30)= -> x*sen(30)=12 -> x== 24cm
cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm
Answer:
Step-by-step explanation:
this is independent
20/50= 2/5= 40% of getting pink, probability of getting 2= 20%
13/50=0.26= 26% of getting blue, probability of getting 2= 13%
17/50=0.34=34% of getting purple, probability of getting 2 = 17%
70%
The coordinates of the point after the two reflections are (0.3,-7/10).
<h3>What is the reflection?</h3>
A reflection is a mapping from an isometric hyperplane with a set of fixed points acting as the reflection's axis or plane from a Euclidean space to itself. A figure's reflection creates its mirror image of that figure in the plane or axis of the reflection.
Given that, the point (-0.3, 7/10) is reflected over the y-axis and then over the x-axis respectively.
The coordinates of the point after the reflection in the y-axis are:
(0.3, 7/10)
Now, the coordinates of the point after the reflection in the x-axis are:
(0.3, -7/10)
Hence, the coordinates of the point after the two reflections are (0.3,-7/10).

Answer:
x=-11
Step-by-step explanation:
Sum of the interior angles of a triangle is 180
(x+51)+60+80=180
(x+51)+140=180
x+51=40
x=-11
