Answer:
AB = 33.78228208
BD = 42.3
AT= 20.33068487
Area= 859.9879701
Step-by-step explanation:
Using the sin rule:
<u>sinA </u> = <u>sinB</u>
a b
If I use A = 90, a= 42.3
B = 53, b= AB
I get AB = 33.78228208 units
Then the diagonal is already 42.3 cm so I think. BD should be 42.3 cm too.
I used the sin rule again for ABD to find AD but by using B as 37° and b as AD.
I get AD = 25.45677548
For ADT,
AD is the hypotenuse.
Now I get from the same sin rule,
A= 90°. a= 25.45677548
B= 53°. b = AT
AT= 20.33068487 units.
Area of rectangle = l×b
= AB × AD
so that gives me 859.9879701 square units
Answer:
−2x^2+6x
Explanation:
You just have to distribute meaning you have to multiply -2x to the equation.
Answer:
(x – h)2+ (y – k)2 = r2
Step-by-step explanation:
Hello!
To find the slope of the given equation, we would need to convert this equation from standard form into slope-intercept form. Our goal, is to get the variable y, on one side of the equation.
Remember that slope-intercept form is written as y = mx + b. In this form, m is the slope and b is the y-intercept.
2x + 4y = 12 (subtract 2x from both sides)
4y = 12 - 2x (divide both sides by 4)
y = 12/4 - 2/4x → y = -1/2x + 3
Therefore, the slope of this equation is -1/2, which is the final choice listed.
