Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.
The 3 inside angles of a triangle must equal 180 degrees.
The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.
Since the 2 bottom angles would be the same, divide 142 by 2 to get x.
X = 142 / 2 = 71 degrees.
Answer:
P(orange)x P(orange)= 5/9 x 5/9= 25/81
Step-by-step explanation:
For this, let's have:
n represent each number, the number after it is its place in sequence
/ means divide
n1 /2 = n2, etc.
First set up the equation 12x-7=4x+9
Get all the x's on one side and number on one side so you have 8x= 16
You get X=2
