Type a digit that makes this statement true. HELPPPP MEEEEE PLZZZZZ!!!
Usimov [2.4K]

Answer:

2

Step-by-step explanation:

Ok so basically you want a number that is evenly divisible by 4. Or in other words 4 x ? = 691,61#

The easiest thing to do is start with a zero there and divide it by 4 to see what you get.

691,610 / 4 = 172,902.5

Since this is not evenly divisible by 4 let's round it up to the next whole number and multiply by 4

4 x 172,903 = 691,612

So the digit you can put on the end of the number is 2

kow [346]

Answer:  b) two sides and the included angle are congruent

<u>Step-by-step explanation:</u>

  RS = QS                 SIDES are congruent

∠PSR ≡ ∠PSQ         ANGLES are congruent

 PS = PS                  SIDES are congruent

ΔPSR ≡ ΔPSQ by the Side-Angle-Side (SAS) Congruency Theorem

Since we know the triangles are congruent, we can state that their parts are congruent:

Congruent-Parts of-Congruent-Triangles are-Congruent (CPCTC)
