The rule for secants tells you
  EC·ED = EB·EA
  (x+4)(x+5) = (x+1)(x+12)
  9x+20 = 13x+12 . . . . . . simplify, subtract x²
  8 = 4x . . . . . . . . . . . . . . add -12-9x
  2 = x

The value of x is 2.

In the diagram the measure of angle 3 is 105 degrees which angle must also measure 105? A.1 B.4 C.6 D.8       I NEED HELP ASAP P
faltersainse [42]

Answer: The correct option is (A). angle 1.

Step-by-step explanation:  In the given diagram, the measure of ∠3 is 105°.

We are to find the angle that must also measure 120°.

We know that the measures of two vertically opposite angles are equal.

In the given diagram, since ∠1 and ∠3 are vertically opposite angles.

So, the measures of ∠1 and ∠3 are equal.

That is,

m∠1 = m∠3.

Also, m∠3 = 105°.

Therefore, m∠1 = 105°.

Thus, the measure of angle 1 must be 105°.

Option (A) is correct.

Two ad agencies want to understand issues that are important to students. Agency A will interview 50 students whose names are ra
cluponka [151]
These ad agencies must focus on their target audience, which are the students. Hence, they should gather data on the pool that will surely comprise of students. For agency B, social media posting is not a good source pool. It's true that students are very participative and opinionated in social media. However, they can't be sure that these are students. Some parents are in social media, as well. Some are working individuals, and some are out of school youth. Unlike agency A, agency B has to sort out profiles first and identify which ones are students. Hence, agency A will produce a fair sample of the student population because it is unarguably true that everyone in the school enrollment data are students.

The answer is B.

Answer:

The one opposite of 100°, as the bigger the angle, the bigger the opposing side, is the biggest.

By the same logic, the one opposite 45° is the next biggest.

Continuing with that, the one opposite the black one (which would equal 35°, I think) is the smallest.
