Answers

Answer:

25

Step-by-step explanation:

z+3z+25=125

4z=100

For the given triangles ΔABC ≈ ΔXYZ, the length of side N is, 45/4

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

The triangle, ΔABC

Triangle ΔABC and ΔXYZ similar,

So,  ΔABC ≈ ΔXYZ

And it is known that

for similar triangles, ratio of lengths of sides are equal for similar triangles

so, AB/AC = XY/XZ

⇒ 5/8 = N/18

⇒ N = 45/4

Hence, the value of N is 45/4

Answer:

39

Step-by-step explanation:

If i'm right, a triangle should add up to 180, so you add 39 and 102 to get 141. Then you subtract 141 from 180 and get 39

Answer:

39

Step-by-step explanation:

Remark

Every triangle has 180 degrees. The three angles must add to 180

Solution

x + 102 + 39 = 180

x + 141 = 180                     Subtract 141 from both sides.

x + 141-141 = 180-141

x = 39

Answers

Answer:

5 can of tomato sauce for $2.39

Step-by-step explanation:

1.49/3 = $0.49

2.39/5 = $0.47

3 cans: divide $1.49 by 3 to get around 0.497 cents.

5 cans: divide $2.39 by 5 and it’s equal to 0.478 cents.

So 5 cans of tomato sauce for $2.39 is cheaper than the 3 cans for $1.49
