Answer: uhhh 54
Step-by-step explanation:
Answer:any number is correct
Step-by-step explanation:
4(3x+1)=12x+4
12x+4=12x+4
12x-12x=4-4
0=0
This equation has no answer.
Actually any number you put in place of x this equation will be true so we can say the answer is
X=infinity
Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
Given:
The figure of a right angle triangle.
To find:
The value of y.
Solution:
in a right angle triangle,
In the given right triangle,
On cross multiplication, we get
Therefore, the value of y is 
units.
Every triangle has a total of 180 degrees. If one angle measure is 100, then 180-100 is 80. This means that the other two angle measures have a total of 80. As angle j and k are equal, we divide 80 by 2, to get 40. This means that the measure of both angle j and k is 40 degrees. The measure of angle j is 40 degrees.
