This is a right angled triangle

I really need someone's help rn

i)

Step-by-step explanation:

i) As it is a right-angle triangle,

ii)From the above equation we get, that x=3 is a solution

Hence, Base= 4x=12

Altitude=5

Hence, Area of a triangle = Altitude X Height X 1/2

= 12 X 5 X 1/2

=30 cm^2

i really dont know

step-by-step explanation:

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
