You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.
But, 3.5^2 + 4.5^2 is not equal to 5.5^2.
Answer:
The Answer is C. false; m =-2 or m=2
Step-by-step explanation:
This is because:
2*2=4 being 4+6=10 Making 2 true, but
-2*-2= 4 as well making it 4+6=10, Making -2 true as well.
Answer: 
Step-by-step explanation:
Given
The two communication mask are 2 km apart
Ubi's home is 500 m east of one of the mask
Suppose its distance from the other's is x
From the figure, we can write
Step-by-step explanation:
a = 2 + 3a + 8
a = 10 + 3a
a - 3a = 10
-2a = 10
a = -5
C) 12V2
12^2 + 12^2 = c^2
144 + 144 = 288
V288 = 12V2
