C= -3 and d=15
I took the 'c' term out of the left side
c multiplied by 4x makes -12x so c must be -3
that means that -3 multiplied by -5 equals d (which is 15)
Answer:
The correct answer is option B. 4√3/3
Step-by-step explanation:
<u>Points to remember</u>
If a right angled triangle with with angles 30°, 60° and 90° then the sides are in the ratio 1 :√3 : 2
<u>To find the value of y</u>
From the figure we can see two right angled triangle.
From the figure we get height 'h' of large triangle is written by,
h : base : 8 = 1 : √3 : 2
Therefore h = 8/2 = 4
Also we can write,
y : h : hypotenuse of small triangle = 1 : √3 : 2
y : 4 : hypotenuse = 1 : √3 : 2
Therefore y = 4/√3 = 4√3/3
The correct answer is option B. 4√3/3
4(-1/2)*(5/4)=-5/8
-29/16——->-41/16
(-5/8,-41/16)
Answer—5/8
