We need a picture please, we cannot see the triangle
(0,5) would be the y intercept because that is when x is 0!
As angle 6y° and angle( 13y - 10 )° are interior angles on the same side of transversal their sum will be equal to 180° .
Then :-
Which means :-
= 13y - 10
= 13 × 10 - 10
= 130 - 10
= 120°
Then angle 6y :-
= 6 × 10
= 60°
As angle 60° and angle 9x + 12° are a linear their sum will also add up to form 180° .
Which can be written as :-
Then :-
= Angle 9x + 12
= 9 × 12 + 12
= 108 + 12
= 120°
Therefore , the value of y = 10 and the value of x = 12 .
Answer:
27 cm
Step-by-step explanation:
So the ratio you have is
width(x) : length (36)= 3:4
Divide 36 (length) by the ratio length. 36÷4=9
They are multiples of nine, so multiply the width by 9 to get the 3.
3×9=27
You have 27:36
If you want to check it, divide both by 9 and you get 3:4
The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
