The part of the proof that uses the justification that angles with a combined degree of 90° are complementary is; Congruent Complements Theorem

<h3>How to prove complementary angles?</h3>

We are given;

m∠1 = 40°

m∠2 = 50°

∠2 is complementary to ∠3

We want to prove that ∠1 ≅ ∠3

Now, when the sum of two angles equals 90°, they are called complementary angles.

Now, looking at the angles, the proof that ∠1 ≅ ∠3 is Congruent Complements Theorem. This is because If two angles are complements of the same angle (or congruent angles), then the two angles are congruent.

<em>Jennifer bought 6 times more than Eunice</em> but half of the total of beads Suin bought.

Eunice: 6 * 585 = 3510

Jennifer bought 6 times more than Eunice but <em>half of the total of beads Suin bought.</em>

<em>Suin: 3510 * 2 = 7020</em>

The product of seven non-zero factors. of which only three are positive. is
IgorC [24]

The answer is A

Step-by-step explanation: This is one of those sneaky questions where you think there is no definite answer, but don't despair. There is an answer. You have 7 numbers 3 of them are positive which means greater than 0. Let's pick them 345 = 60 That part's easy. Those 3 numbers give a plus result. Now try the other 4 numbers -3 -2 - 1-4 Do you see what's going to happen. You have -3* - 2 = 6 then you get - 1*-4 = 4 All of a sudden you get a positive result 6 * 4 = 24 60 * 24 = 1440 So the answer is any 3 plus numbers multiplied by 4 minus numbers gives a plus result.

What is the value of n
Over [174]
So firstly you are given the external angles, to find the internal angles, you do 180-133=47

180-142=38
the internal angles in a triangle add up to 180, therefore it is
47+38=85
180-85=95
because you have to find the external angle=n you then need to take 95 away from 180
180-95=85
so the answer is A
