Answer:

Step-by-step explanation:
Given
sinΘ =
= 
Then the hypotenuse = 5 and one leg of the right triangle is 3
Using Pythagoras' identity to find the second leg (x)
x² + 3² = 5²
x² + 9 = 25 ( subtract 9 from both sides )
x² = 16 ⇒ x = 4
cosΘ =
= 
Answer:
the equation: 2x+3+2x+3+2x= 36
x=5
the length of the congruent sides
15
the length of the third side
10
Step-by-step explanation:
i'll add this later hold on
Answer:
4
Step-by-step explanation:
First, we find the greatest common factor of 36 and 16.
36 = 2^2 * 3^2
16 = 2^4
GCF = 2^2 = 4
He can make 4 plates.
4y=5x+8
5y=-2x+30
the y always goes first. then the equal sign. next is x and finally just the digit which is also known as "b".
