Answer:
third angle =180-two congruent angles. is expression.
Answer:
KI=11.25 and HI=6.75
Step-by-step explanation:
Consider the below figure attached with this question.
According to Pythagoras Theorem:

Use Pythagoras in triangle HKL




Taking square root on both sides.

Let length of HI be x.
LI = 12+x
Use Pythagoras theorem in ΔKLI,




Use Pythagoras theorem in ΔHKI,


From (1) and (2) we get



Hence, the measure of HI is 6.75 units.
Substitute x=6.75 in equation (2).


Taking square root on both sides.


Hence, the measure of KI is 11.25 units.
25% is equal to

. To get 25% of 300, we multiply 300 by either 0.25 or

. This gives us
Answer:
In the figure below :
d = 2.08, e = 5, c = 5.42 , a = 22.78°, b = 67.22°
Step-by-step explanation:
Side lengths :

By pythagoras theorem,

Now to find angles,

Un número primo es un número entero mayor que 1, cuyo sólo dos factores de números enteros son 1 y en sí.
