Answer:
I can help with Q "4" as -
It uses triangle congruence test - here we use - SAS, as
one side is equal as it is given
both the angles are 90 degree
and they share a same side
so -
8x = 6x + 5
8x - 6x = 5
2x = 5
x = 2.5
RU = 6x+ 5 = 6 (2.5) + 5 = 20
( I am not so sure but I think this is the answer )
Answer:
A
Step-by-step explanation:
The degree is cubic (3) and there are 3 terms X^3, X^2, X
The first answer is 80, and the second answer is still 65.5. Hope this helps!
