Step-by-step explanation:
the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.
but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say
180 = ACB + ABC + CAB
180 = y + 180 - x + CAB
0 = y - x + CAB
x = y + CAB
x - y = CAB
therefore, the second answer option is correct.
Answer:
A triangle

Please mark me as brainliest
4½ = 9/2
1 2/5 = 7/5
9/2 * 7/5 = 63/10 = 6 3/10
Answer:
this is the formula u can use it on any Pythagoras theorm problem
Our goal is to get r all by itself on one side of the equals sign. To do this, we'll first add s to both sides
k=2r-s
+s +s
k+s=2r
Now, to get r alone, we need to get rid of the 2. Since 2 is multiplied by r, we need to divide it from both sides to get r alone.
k+s=2r
/2 /2
(k+s)/2=r
Since there are no numbers, that's the final answer.
