In order for two triangles to be considered as similar, they must be
- equiangular (all angles equal)
- all sides equal (sss)
- if two pairs of two sides are in proportion or are matching, and one included angle is equal



Q4a) yes, because all the angles are equal (equiangular)


b) yes, because all sides are in matching ratio (so 10/5 is 2, 6/3 is 2 and 8/4 is 2; so they are in matching ratios)


c) yes, because if you plus 60 and 70, you get 130. Minus 180 and 130, you get 50. So, in both triangles the angles will be 60,70 and 50; so they're equiangular

PLEASE HELP!
fenix001 [56]

Answer:

No

Step-by-step explanation:

No because (1,2) falls on the line, and the line is a dotted line, which means that any point on the line is not a solution to the inequality.

The function f(x) is shown on the graph.
Sever21 [200]

The value of f(0) is 12.

<h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

By considering the graph we have to find f(0) which means we have to find that point where x- coordinate is zero.

Also, which shows that 12 the function f(x)

So, taking the point is (0,12) we can get f(0)= 12.

In the equation 2y=18, determine which property of equality will be used to isolate the variable. Choose the best answer. A. Mul
mixer [17]

Answer:

(C) Division Property of Equality

Step-by-step explanation:

Looking at the equation 2y=18, we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.

The Division Property of Equality states that if we have an equation, a=b, then a\div c = b\div c.

So, that means 2y\div 2 will be equal to 18 \div 2, which is 9.

Hope this helped!
