Answer:
2/4a-4
Step-by-step explanation:
dividing 2/4a-4 is =1/2a-4
Answer:
x=18
Step-by-step explanation:
S=(n-2)180
S=(5-2)180
S=3x180
S=540
540=(9x-6)+(3x+23)+95+((7x-4)+90
540=19x+198
540-198=19x
342=19x
342/19=x
x=18
It looks like it goes through (0,-3) and (1,2), so the gradient is (change in y)/(change in x) ->
(-3-2)/(0-1) = 5
So y=5x+b
Then as we know it passes the y axis at (0,-3) so b= -3
So we have y=5x-3
Answer:
2) ∠SDH and ∠SDT are right angles because SD ⊥ HT.
3) 
as it is given in the question.
4) 
is the reflexive property.
5) ΔSHD ≅ ΔSTD by RHS congruency.
Step-by-step explanation:
Given in the question:
In ΔSHD and ΔSTD
(Given)
(SD ⊥ HT)
(Common)
Therefore, 
(By RHS rule)
Reflexive property of congruency is defined as the property in which something is equal to itself. Hence, the reflexive property of these two triangles is
