Find x, y, and z

x = 39
x = 29
y = 61
y = 29
z = 61
z = 29

Answers

answer:

x = 29

y = 29

z = 61

step-by-step explanation:

all angles in a triangle must equal 180 degrees.

we were already given the angle degree of 61 degrees so we must include that in our formula to determine the degree of y.

the line in the middle already gives us two more angles because they both are 90 degrees for being a perfect quarter turn.

so to figure out y,

we must add 61+90 and then subtract the sum of that from 180.

so, 61+90 = 150 and 180-151 = 29

therefore,

we can conclude that y = 29

now, to determine the degrees of x and z we do the same thing.

we already know one angle equals 90 degrees.

180-90 = 90

that concludes that x and z must have a sum of 90.

if we use our choices,

39+61 = 100 (no)

39+29 = 68 (no)

29+61 = 90 (CORRECT)

29+29 = 28 (no)

therefore, x = 29 and z = 61

so, in total :

x = 29

y = 29

z = 61

hope this helps :)

Mr. Griffin wants to help his students maintain complete concentration throughout their long calculus exam. To achieve this goal, he should structure the first few questions to: A) Gradually increase in difficulty. B) Cover a wide range of topics. C) Be concise and to the point. D) Include interesting real-life applications.

Answers

Answer:

A. Gradually increase in difficulty

Step-by-step explanation:

Option A is the most effective choice because structuring the first few questions of a long calculus exam to gradually increase in difficulty can help students ease into the exam, build confidence, and maintain their concentration. Starting with easier questions allows students to warm up and gain momentum, which can reduce anxiety and increase their focus. This approach aligns with best practices in assessment and educational psychology, as it promotes a smoother transition into more challenging material, ultimately supporting better concentration and performance throughout the exam.

Final answer:

To maintain student concentration during a long exam, the first few questions should gradually increase in difficulty. This approach builds student confidence and eases them into the problem-solving process, potentially reducing test anxiety and encouraging perseverance through harder problems.

Explanation:

To help his students maintain complete concentration throughout their long calculus exam, Mr. Griffin should structure the first few questions to be gradually increase in difficulty. This approach helps students to gain confidence as they successfully solve the initial questions which is likely to carry them through the rest of the exam and maintain their concentration.

Beginning with easier questions allows the students to 'warm up' and transition their mind into the calculus mode. Then, as the questions become increasingly difficult, students are better prepared to tackle them because they've eased into the problem-solving process instead of being hit with the most challenging problems right off the bat. This approach can reduce test anxiety and encourage perseverance through the more difficult problems towards the end of the test.
