The type of relationship that angle a and angle b have is that they are complementary.

<h3>What are Complementary Angles?</h3>

A right angle equals the measure of 90 degrees. If two angles equals a right angle, then their sum equals 90 degrees. Complementary angles have a sum of 90 degrees, therefore, if two angles form a right angle, then they are a pair of complementary angles.

In the image given, angle a and angle b form a right angle. Thus, the sum of angle a and angle b equals 90 degrees. This means they are complementary angles.

Therefore, the type of relationship that angle a and angle b have is that they are complementary.

A group of tourists spend $168 to rent snorkels and find. A total of 10 snorkels and 12 pairs of fins are rented. Renting a snor

WITCHER [35]

Answer:

Cost to a rent a snorkel $=\$ 12$ , Cost on 10 rent snorkel $=\$ 120$

Step-by-step explanation:

Given,

Tourist spend on rent snorkel and fin= $\$ 168$

10 snorkel and 12 pairs of fin

Let the cost to rent a snorkel be = $\$$ x

and cost of a pair of fin is = $\$$ y

x=3y (given condition)

$10x+12y=168$

$10\times 3y+12y=168$

$30y+12y=168$

$42y=168$

$y=168/42$

$y=4$

Cost of a pair of fin= $y=\$ 4$

$x=3y$

$x=3\times 4$

$x=12$

Cost of rent a snorkel $=\$ 12$

Total cost of a rent snorkel

$=10\times 12$

= $\$ 168$

Solve the equation

UNO [17]

Answer:

x = 10

Step-by-step explanation:

2x/3 + 1 = 7x/15 + 3

<em><u>(times everything in the equation by 3 to get rid of the first fraction)</u></em>

2x + 3 = 21x/15 + 9

<em><u>(times everything in the equation by 15 to get rid of the second fraction)</u></em>

30x+ 45 = 21x + 135

<em><u>(subtract 21x from 30x; subtract 45 from 135)</u></em>

9x = 90

<em><u>(divide 90 by 9)</u></em>

x = 10

<h2>Another solution:</h2>

2x/3 + 1 = 7x/15 + 3

<u><em>(find the LCM of 3 and 15 = 15)</em></u>

<u><em>(multiply everything in the equation by 15, then simplify)</em></u>

10x + 15 = 7x + 45

<u><em>(subtract 7x from 10x; subtract 15 from 45)</em></u>

3x = 30

<em><u>(divide 30 by 3)</u></em>

x = 10

How to show opposite sides on a parallelogram are congruent

Marta_Voda [28]

Answer:

I am attaching a image to understand my proof.

Step-by-step explanation:

PROVE:-

AB = DC

AD = BC

∠ ABD = ∠ BDC (alternate angles are equal )

∠ DBC = ∠ ADB (alternate angles are equal )

∴ Δ ADB ≅ Δ CBD ( by ASA rule )

DC = BA ( corresponding sides of ≅ Δ )

AD = CB ( corresponding sides of ≅ Δ )

Hence it is proved that opposite sides of parallelogram are congruent )
