If they are vertical angles, they are equal.

5x - 24 = 3x + 24                      Add 24 to both sides

5x -24 +24 = 3x + 24 + 24       Combine

5x =   3x + 48                           Subtract 3x

5x - 3x = 3x-3x + 48                Combine

Answer:

YZ = 8.5∠X = 70.5°∠Z = 19.5°

Step-by-step explanation:

There are a couple of ways to do this. We can find YZ using the Pythagorean theorem, or we can find it using trig functions.

We know from SOH CAH TOA that ...

  Cos = Adjacent/Hypotenuse

  cos(X) = 3/9 = 1/3

  X = arccos(1/3) ≈ 70.5°

Angle Z is the complement of this, so is ...

  Z = 90° -70.5° = 19.5°

__

The length of side YZ can be found from ...

  Sin = Opposite/Hypotenuse

  sin(X) = YZ/XZ

  YZ = XZ·sin(X) = 9·sin(70.5°) ≈ 8.485 ≈ 8.5

__

In summary, ...

  YZ = 8.5; ∠X = 70.5°; ∠Z = 19.5°

* 10. You have 39 math and science problems for homework. You
have 15 more math problems than science problems. Use the
model to write a system of linear equations. How many problems
do you have in each subject?

Answers

Answer:

Science problems= 12

Math problems= 27

Step-by-step explanation:

If

x= math problems for solving

y= science problems for solving

x+y=39

y=x-15

Using substitution method:

x+(x-15)=39

2x-15=39

2x=39+15

x=(39+15)/2

x=27

Having "x" lets find out "y" value.

x+y=39

27+y=39

y=39-27

y=12

The secretary could tell in a moment that such backwoods, country hicks had no business at Harvard and probably didn't even deserve to be in Cambridge. She frowned. "We want to see the president", the man said softly. "He'll be busy all day," the secretary snapped. "We'll wait," the lady replied.For hours, the secretary ignored them, hoping that the couple would finally become discouraged and go away. They didn't. And the secretary grew frustrated and finally decided to disturb the president, even though it was a chore she always regretted to do. "Maybe if they just see you for a few minutes, they'll leave," she told him. And he sighed in exasperation and nodded. Someone of his importance obviously didn't have the time to spend with them, but he detested gingham dresses and homespun suits cluttering up his outer office. The president, stern-faced with dignity, strutted toward the couple. The lady told him, "We had a son that attended Harvard for one year. He loved Harvard. He was happy here. But about a year ago, he was accidentally killed. And my husband and I would like to erect a memorial to him, somewhere on campus."The president wasn't touched - he was shocked. "Madam," he said gruffly, "We can't put up a statue for every person who attended Harvard and died. If we did, this place would look like a cemetery.""Oh, no," the lady explained quickly, "We don't want to erect a statue. We thought we would like to give a building to Harvard.The president rolled his eyes. He glanced at the gingham dress and homespun suit, then exclaimed, "A building! Do you have any earthly idea how much a building costs? We have over seven and a half million dollars in the physical plant at Harvard." For a moment the lady was silent. The president was pleased. He could get rid of them now. Then the lady turned to her husband and said quietly, "Is that all it costs to start a University? Why don't we just start our own?"Her husband nodded. The President's face wilted in confusion and bewilderment. And Mr. and Mrs. Leland Stanford walked away, traveling to Palo Alto, California, where they established the University that bears their name, a memorial to a son that Harvard no longer cared about.QUESTION: Why did the president of the university look down upon the couple? aA. He thought they were going to cause problems because they looked dangerous. bB. He didn't think they were important enough to talk to because they looked poor. cC.
