18 Geometry question: Use an algebraic equation to find the measure of each angle that is representative in terms of X

Dmitrij [34]

Answer:

12x - 28° = 116°

7x + 32° = 116°

Step-by-step explanation:

12x - 28° and 7x + 32° are vertical angles. Vertical angles are congruent.

Therefore, to find the measure of each angle, we have to set each equation equal to each other as follows:

12x - 28° = 7x + 32°

Collect like terms

12x - 7x = 28 + 32

5x = 60

Divide both sides by 5

5x/5 = 60/5

x = 12

✔️12x - 28°

Plug in the value of x

12(12) - 28

= 144 - 28

= 116°

✔️7x + 32°

7(12) + 32

= 84 + 32

= 116°

A car's rear windshield wiper rotates 140°. the total length of the wiper mechanism is 25 inches and the length of the wiper bla

koban [17]

Here we use the formula of area of sector, which is

$Area =( \frac{ \theta}{360}) \pi r^2$

Substituting 140 for theta, 11 for radius, we will get

$Area = ( \frac{140}{360}) \pi *11^2$

$Area = 147.8 inches^2$

And that's the required area wiped by the wiper blade .

A jar containing only nickels (n) and dimes (d) contains a total of 60 coins. The value of all the coins in the jar is $4.45.

cestrela7 [59]

Answer:

n + d = 60

0.05n + 0.1d = 4.45

The jar contains: 31 nickels and 29 dimes.

Step-by-step explanation:

Numbers of coins: n nickels and d dimes

Total number of coins: n + d

Total number of coins: 60

Equation 1: n + d = 60

Values of the coins:

n nickels are worth 0.05n

d dimes are worth 0.1d

Total value of all coins: 0.05n + 0.1d

Total value of coins: $4.45

Equation 2: 0.05n + 0.1d = 4.45

System of equations:

n + d = 60

0.05n + 0.1d = 4.45

Solve the first equation for n.

n = 60 - d

Substitute 60 - d for n in the second equation.

0.05n + 0.1d = 4.45

0.05(60 - d) + 0.1d = 4.45

3 - 0.05d + 0.1d = 4.45

3 + 0.05d = 4.45

0.05d = 1.45

d = 29

There are 29 dimes.

n + d = 60

n + 29 = 60

n = 31

There are 31 nickels.

The jar contains:

31 nickels and

29 dimes.
