Answer:
90 degrees
Step-by-step explanation:
Sum of the angles in a triangle = 180°
Opposite angles are equal
For two parallel lines and a transversal,
corresponding angles are equal, and
alternate angles are equal.
45+45=90.
180-90=90
Plus, you can see that the angle forms a perfect 90 degree angle.
Answer:
Step-by-step explanation:
ΔPQS, ΔRQP and ΔRPS are similar (AA). Therefore the sides are in proportion:
We have:
Substitute:
<em>cross multiply</em>
Use the Pythagorean theorem:
Substitute:
Answer:
j=7
Step-by-step explanation:
Answer:
Because for the first problem you would have to simplify 8 divided by 2 into 4 in which 12 - 4 = 8 then you would have to simplify 12 - 4 to 8 which 8 = 8
Because for the second problem you would have to simplify 12 - 8 to 4 which 4 divided by 2 = 2 then you would have to simplify 4 divided by 2 to 2 which 2 = 2
There are parentheses which if there weren't you would get a different answer
