How do u solve this bruv Pls help unfortunately i need to show work

Answer:

A=60

Step-by-step explanation:

Complementary means it's 90 degrees

60 and 30 have a 30 degree difference.

The measure of angle a is 60°

What are Complementary Angles?

When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

Given data ,

The two angles are a and b

a and b are complementary

So , a + b = 90°

The difference of angle a and b is 30°

The greater angle is a and smaller angle is b

So , a - b = 30°

Now , we have two equations

a + b = 90°

a - b = 30°

Adding both equations , we get

2a = 120°

Divide by 2 on both sides , we get

a = 60°

Hence , the measure of angle a is 60°

The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

To simulate an event that has a probability of success of 20%, we need to randomly generate numbers from 0 to 9 such that there is a 20% chance of getting a "success" number.

Since there are 10 possible numbers to choose from, 20% of them would be 2 "success" numbers.

So, any group of numbers that contains two "success" numbers out of 10 would represent a success.

For example,

The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

Other groups with two "success" numbers would also be valid.

Thus,

The group {2, 5, 8, 1, 3, 7, 0, 9, 4, 6} contains two "success" numbers (2 and 5) and eight "failure" numbers, so it could represent a success.

Answer:

-12

Step-by-step explanation:

To solve for this question, you have to isolate the variable u. To do this, divide both sides by 7/4 to isolate the u. Then your equation should be u= -21 divided by 7/4. This would simplify to -21 times 4/7. This would get you -12. Hope this helps :)

Answer:

They are perpendicular

Step-by-step explanation:

the first graph has 1/3 as its slope.

The inverse of 1/3 is the negative reciprocal, or -3/1, which is the same as -3.

Thus, as the second graph’s slope is -3, it is the inverse of the first graphs slope, which means the two graphs represent lines which are perpendicular to each other.

we know,

slope = y2 - y1 / x2 - x1

now,

→ -9 - (5)/ 3 - (-3)

→ -4/6

→ -0.66....
