Answer:
Step-by-step explanation:
Let r and j represent Riley's hours and Jace's hours, respectively. The equations could be ...
25r +30j = 460
r - j = 3
__
The solution is (r, j) = (10, 7).
Answer:
∡BCE = 60
Step-by-step explanation:
Here, we want to find the angle marked BCE
From our diagram, the angle marked BCE is y
Looking at triangle BCE, we have the right angle, an angle measure of 30 and the angle marked y which we say is BCE
mathematically, the sum of all these will give 180 as the sum f the interior angles of a triangle is 180
Thus, we have that;
y + 30 + 90 = 180
y = 180-120
y = 60
Answer:
x = 40 *
meters
Step-by-step explanation:
You have a 30-60-90 right triangle in this situation.
the height of this triangle is 40 meters
the opposite angle is 30 degrees.
use the tangent.
let x = distance between boat and cliff
tan 30 = 40/x
1/root (3) = 40/x
x = 40 *
meters
