What is the value of y?
y +10°
50°
A. 500
B. 40°
C. 60°
ОО
D. 300

B

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

y + 10 + 2y + 50 = 180 , that is

3y + 60 = 180 ( subtract 60 from both sides )

3y = 120 ( divide both sides by 3 )

y = 40 → B

B

Step-by-step explanation:

50° + (Y+40°) + 2Y= 180°

180°-50°-40°=3Y

90÷3=3Y÷3

Y=30

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
