The two triangles are similar. What is the value of x? Enter your answer in the box. x = Two right triangles, one smaller than t

he other, back to back, so that their right angles form a straight angle. The two acute angles along the straight angle are congruent to each other. The overlapping part of the legs is labeled 20. The part of the overlapping side that extends above the smaller triangle is labeled 8. The leg of the smaller triangle that is a ray of the straight angle is labeled 3 x. The leg of the larger angle that is a ray of the straight angle is labeled 4 x plus 2.

<span>x = 4
   Given the description of the triangles, you have 2 similar right triangles. The smaller triangle has a height of 20 and a base of 3x, while the larger has a height of (20+8) = 28 and a base of 4x + 2. We wish to determine the value of x. Since the triangles are similar, the ratio of corresponding sides will be a constant. So:
 20/28 = (3x)/(4x+2)
 (4x+2)20/28 = (3x)
 (20/28)*4x+(20/28)*2 = (3x)
 (80/28)*x+(40/28) = (3x)
 (20/7)*x + 4/7 = 3x
 4/7 = 3x - (20/7)*x
 4/7 = (21/7)x - (20/7)*x
 4/7 = x/7
 4 = x
   So the value of x is 4.</span>

There are 120 students in the seventh grade. Seventy percent of these students are involved in extracurricular activites. How ma
Tanzania [10]

First, turn 70% into a decimal by dividing 70 by 100.

70% ⇒ 0.70

Multiply 120 by 0.70.

120 × 0.70 = 84

Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.

120 - 84 = 36

<h2>Answer:</h2>

<u>36 seventh grade students are not involved in extracurricular activities.</u>
