Answer:

The first option is correct: Angle 2 through 5

Step-by-step explanation:

Both angles 2 and 5 are directly vertical or opposite to each other and are the only angles that are proportionate/equal sizes.

The other three options are incorrect because angles 4 and 3 are not the same equal value and are right next to each other making them not vertically across.

angles 1 and 5 are close to being vertical but are not the same size as angle 1 is much smaller than angle 5.

angles 6 and 1 are next to each other making them not vertically to each other and angle 6 is much larger than angle 1.

the correct answer is angles 2 and 5, the first option.

Hector is dividing students into groups for an HR wants to divide the boys and girls so that each group has the same number of t

Roman55 [17]

Answer:

7 groups, 3 boys and 8 girls

Step-by-step explanation:

Let total number of groups be $x$

and total hikers in one group be $y$

if number of girls and boys in every group is same, then

$\frac{21}{x} + \frac{56}{x} = y$

$\frac{21 + 56}{x} = y\\x*y = 77$ ....(1)

from (1) $x$ will either be 11 or 7

for $x = 11$ the values won't be real.

For $x = 7\\y = \frac{77}{7} \\y = 11$

so there will be 7 groups with 11 hikers in each groups and every group will have $\frac{21}{7} = 3$ boys and $\frac{56}{7} = 8$ girls

2 triangles are shown. The first triangle has side lengths 35, 20, and 20. The second triangle has side lengths x, 44, 44.

Ad libitum [116K]

The value of x is 77 cm which will make the triangles similar by SSS similarity theorem

Given length of the three sides of one triangle are 35 , 20 and 20

and length of the three sides of another triangle are x, 44,44

We need to find the values of x by using SSS Similarity theorem

We know that triangles are are similar by side - side - side similarity creation and hence the sides are in the same ratio

As both the triangles are isosceles triangles

Therefore ,

x/35 = 44/20=44/20 (Using ratio)

Solving the equation we get

x=44*35/20

x= 77

Hence the value of x is 77cm
