Answer:
m<ABC = 116°
m<CDE = 67°
Step-by-step explanation:
✔️m<ABC = 180 - m<BAD (adjacent angles of a parallelogram are supplementary)
m<ABC = 180 - 64° (Substitution)
m<ABC = 116°
✔️m<CDA = m<CDE + m<ADE (angle addition postulate)
m<CDA = m<CDE + 49°
m<CDA = m<ABC (opposite angles of a parallelogram are congruent)
m<CDE + 49° = 116° (substitution)
m<CDE = 116° - 49° (Substraction property of equality)
m<CDE = 67°

Answer:
The answer is 51.
K^2+ K ^2 = H^2
32^2+ K^2= 62^2
1024+ K^2 = 3600
1024 +K^2-1024= 3600-1024
K^2 = 2576
2576 square root= 50,754
so it is 51

Answer:$66.00</h2>
Step-by-step explanation:first we need multiply :D I will use the formula I =prt
principal= $500
rate=3.3%
time= 4 years
but we need to convert the percent, 3.3%, to a decimal
3.3%=0.033 or .033
now we multiply !
500 × 0.033 × 4 = 66 = $66.00
Given:
The functions are:
To find:
The rational expression for 
.
Solution:
We have,
Now,
![[\because a^2-b^2=(a-b)(a+b)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29%5D)
Therefore, the required rational expression for is 
.
The property that justifies multiplying through eqn(2) by -2 is;
the rationalization to align the coefficients of x in both equations with a view to eliminating the terms in x.
It depends and the measurement of the angle.

or
45-45-90
Also, sometimes you can use Pythagorean theorem
