Answer:
<em>y = 12.3 cm</em>
Step-by-step explanation:
This is a right triangle, so we can use sin,cos, or tan to solve this.
First, with respect to the angle 35 degrees, we can say "y" is the "adjacent side".
Also, the hypotenuse is given as 15.
<em>Which trig ratio relates adjacent and hypotenuse? That is COS. So we can write and solve the equation below:</em>

<em>y = 12.3 cm</em>
Answer:
The system has two solution
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system of equations by graphing
Remember that
The solution of the system of equations is the intersection point both graphs
There are two point of intersection between the two graphs
see the attached figure
therefore
The system has two solution
Answer:
112 m
Step-by-step explanation:
The area (A) of a square is
A = s² ( s is the length of side )
Here A = 784 , then
s² = 784 ( take the square root of both sides )
s = = 28
Then
perimeter = 4s = 4 × 28 = 112 m
