Answer:
48
Step-by-step explanation:
12/20 = x/80
20x = 960
x = 48
Answer:
-2y
Step-by-step explanation: First, multiply 12 with x and y. Then do the property of substitution and add 12x and 12y with -14y and -12x
Its a 3,4,5 triangle. This is a special right triangle, so x=6, 3*2, 8 is given, and y=10, 5*2
Given:
The figure of a right angle triangle.
To find:
The value which is equal to r÷q.
Solution:
In the given right triangle, the length of the hypotenuse is q units.
For angle x degrees, perpendicular is p units and base is r units.
For angle y degrees, perpendicular is r units and base is p units.
In a right angle triangle,
So,
Therefore, the value of r÷q is equal to siny or cosx. So, the correct option is C.
