Zahra plans to draw a triangle with angles measuring 50, 60, and 70. which is true about zahra’s plan?
a. zahra cannot make a triangle with these angle measures.
b. zahra can only draw one unique triangle with these angle measures.
c. zahra can make exacty two triangles with these angle measures.
d. zahra can make more than one triangle with these angle measures.

OPtion A Zahra cannot make a triangle with these angle measures.

Step-by-step explanation:

To draw a triangle we must have atleast 3 independent dimensions

Here only 2 are given as third angle depends on first 2.

Hence Zahra cannot make a triangle with these angle measures.

If at all she wants to draw she has to assume some side atleast one side and make triangle

But this is infinite as she can do for any size of her choice.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
