The answer to Em um triângulo retângulo a hipotenusa mede 15 cm e um dos catetos mede 12 cm.Qual é o perímetro desse retângulo?
<span><span><span>borda a =12 </span>unidades
</span><span><span>borda b =9 </span>unidades
</span><span><span>borda c =15 </span>unidades
</span><span><span>ângulo A =</span>53.1 graus
</span><span><span>ângulo B =36.9 </span>graus
</span><span><span>área=54 </span>square </span></span>unidades
Agora temos que
Determinar o comprimento da base do triângulo.
Calcula-se a altura do triângulo.
Multiplicar o comprimento da base por o comprimento da altura.
Multiplique por dois.

Answer:
Yes, the right angle is angle B
Step-by-step explanation:
we have
Plot the vertices
see the attached figure
we know that
If triangle ABC is a right triangle
then
Applying the Pythagoras Theorem
the formula to calculate the distance between two points is equal to
<em>Find the distance AB</em>
substitute in the formula
<em>Find the distance BC</em>
substitute in the formula
<em>Find the distance AC</em>
substitute in the formula
Verify the Pythagoras theorem
---> is true
therefore
Is a right triangle and the right angle is B

Answer:
9. Triangle ABQ is congruent to Triangle BAP because of SAS congruency
10. x=5, y isn't shown anywhere
Step-by-step explanation:
9. The side AB is shared between the two triangles.
It is given that angle A and angle B are congruent.
It is given that AQ is congruent with BP.
Using these three, you can say that Triangle ABQ is congruent to Triangle BAP because of SAS congruency.
10. 7x-4=31 (given)
x=5
Do the same thing with y.
