Let's check with the pythagoras theorem,
65² = 33² + 56²
4225 = 1089 + 3136
4225 = 4225
As it obeys it, It is a right angle triangle.
Hope this helps!
Answer:
∠1 = 23°
Step-by-step explanation:
∠WXZ = ∠WXY + ∠YXZ
Note that ∠2 = 4∠1 ( angle 2 is 4 times angle 1 )
Hence
4∠1 + ∠1 = 115
5∠1 = 115 ( divide both sides by 5 )
∠1 = 23°
Answer: the answer is a 12
Step-by-step explanation:
X^2 + 8x + 3
= (x + 4)^2 - 16 + 3
= (x + 4)^2 - 13 Answer.
You divide the + 8 by 2 to get the +4 and you then subtract 4^2 ( which is the -16).
