We can use pythagorean theorem to find the side of one of the triangles/

12^2 + x^2 = 15^2
x = 13

Since there are two of these triangles:

x = 13+13
x = 26

Hope this helps!

kvv77 [185]

Answer:

90.75%

Step-by-step explanation:

Given;

Of the total final score;

Quizzes = 15%

Exam = 55%

Project = 25%

Attendance = 5%

Resolving the values of each section of the total score;

she had perfect attendance to class. 100% attendance;

Attendance = 5% of total score

She got extra credit on her project with a score of 26 out of 25 possible points.

Project = 26/25 × 25% = 26%

80, 85, and 96 on the first three exams,each worth 100 points;

Total exam score = 80+85+96 = 261 out of 300

Of the total score;

Exam = 261/300 × 55% = 47.85%

At mid-semester Juanita scored 119 out of 150 points on quizzes.

Quizzes = 119/150 × 15% = 11.9%

Total exam score is;

= Quizzes+exam +project+attendance

= 11.9% + 47.85% + 26% + 5%

= 90.75%

What is property of equality

Sauron [17]

Answer:

Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division.

Please if your answering it please i need it step by step please

salantis [7]

I) there are 360 degrees in a circle. So subtract all the numbers from 360 to get the angle for econ.

That angle is 65 degrees

ii) If 95 degrees represents 228 books, then 360 degrees represents "x" (total) books. So we have an equation:
95 = 360
228 x

Solve for x, and we get x = 864

iii) The percentage is 80 degrees out of 360 degrees or 2/9 or roughly 0.222 or 22.2%
