Answer:
a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.
Answer:
I believe the answer is X=2.5
Step-by-step explanation:
7+2=9
so now we have to find what X would be so we can do the second equation
So we know that the second equation must equal 6 because 9+6=15
So now we experiment with different numbers for X
if we did 2, the new equation would be 2x2+1 which is 5, too low
if we did 3, the new equation would be 2x3+1 which is 7, too high
So we need something in the middle
in the middle of 5 and 7 is 6 which is the number we need
so to get 6 we need something in between 2 and 3, which in 2.5
hope this helped!
Answer:
Step-by-step explanation:
Since ∆ABD is similar to ∆CBE, therefore, the ratio of their corresponding side lengths would be equal to each other. Thus:
BD = 12 cm
BE = x
AD = 27 cm
CE = 23.4 cm
Plug in the values
Cross multiply
Divide both sides by 27
