Answer:
Step-by-step explanation:
we know that
The area of the trapezoid is equal to
step 1
Find the measure of angle DAE
m∠ADC+m∠DAE=180° -----> by consecutive interior angles
we have
m∠ADC = 134°
substitute
134°+m∠DAE=180°
m∠DAE=180°-134°=46°
step 2
In the right triangle ADE
Find the length side AE
cos(∠DAE)=AE/AD
step 3
In the right triangle ADE
Find the length side DE
sin(∠DAE)=DE/AD
step 4
Find the area of ABCD
we have
substitute
Answer:
1) 
2) 
Step-by-step explanation:
You can factorize the quadratics equations by applying the proccedure shown below:
1) 
Find two number whose sum is 3 and whose product is 2.
These would be 1 and 2.
Rewrite it as folowing:
2) 
Find two number whose sum is 15 and whose product is 50.
These would be 5 and 10.
Therefore, you can rewrite it as folowing:
Hello
Your answer is
0.581
And remember,any number divided by 10,100,1000 and its smaller it will be the same number,but in decimal form
Good luck!
