Answer:
60 square km
Step-by-step explanation:
First, seperate the figure into two as a rectangle and a trapezium by drawing a line from the vertex between the lines which are 8km and 5km long until it reaches the line on the bottom. (11km) Then, find the area of the rectangle by multiplying 8 by 6, which gives an answer of 48 square km. Then, find the area of the trapezium using the equatiuon 1/2 (a+b) h. Here, a and b are the two parallel lines of the trapezium, which are the lines 2km and 6 km long, and h means the perpendicular height which is 3km long (by substracting 8 from 11, you get 3). you get the answer as 12 square km. finally, add up 12 and 48 to get 60 square km.

D is on side AB of triangle ABC. We know triangle ABC ~ triangle ACD and angle A = 48 degrees. If BC = CD what is angle B in degrees
Answers
Answer:4/6
Step-by-step explanation:
The measure of angle ∠B will be 66 degrees.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
D is on side AB of triangle ABC. We know triangle ABC is similar to triangle ACD and angle A = 48 degrees. If BC = CD.
∠ABC = ∠ACB = x (Isosceles triangle property)
In △ABC, the angle sum is 180°. Then we have
∠ABC + ∠ACB + ∠ABC = 180°
x + x + 48° = 180°
2x = 132°
x = 66°
Then
∠BCA = ∠BCD + ∠DCB = 66°
∠BCD = 66° − 18°
∠BCD = 48°
Now, In ΔBCD, then we have
∠BCD + ∠BDC + ∠DBC = 180°
48° + ∠BDC + 66° = 180°
∠BDC = 66°
We know that ∠BDC = ∠DBC,
∠DBC = ∠BDC
∠DBC = 66°
The measure of angle ∠B will be 66 degrees.

For the function f(x)=5(x+10), find
f −1(x).
Answers
Answer: f-1(x) = x/5 - 10
Shortend: f(x)=5(x+10), f-1(x) = x/5 - 10
Steps:
The inverse can be found algebraically by switching x for y and y for x in the equation. You must then isolate y.
[tex]f(x)=5x+10\\y=5x+10\\x=5y+10\\x-10=5y\\\frac{x-10}{5} =y\\[/tex]

Answers
Answer:
40° and 50°
Step-by-step explanation:
90=(x+10)+x
90=2x+10
80=2x
40=x
Therefore the answer is,
40 and 40+10
40° and 50°
Answer:
50° and 40°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other is x - 10
x + x - 10 = 90
2x - 10 = 90 ( add 10 to both sides )
2x = 100 ( divide both sides by 2 )
x = 50
x - 10 = 50 - 10 = 40
The angle measures are 50° and 40°
