What is m angle DFC​

Mathematics
2 answers:
const2013 [10]3 years ago
5 0

Answer:

m∠DFC=80°

Option 2 is correct

Step-by-step explanation:

In the given figure, BE and AD are straight line.

If two lines intersect then makes vertically opposite angles.

Therefore,

\angle AFE=\angle BFD

But ∠AFE=125°

We can split ∠BFD into two adjacent angle.

\angle DFC+\angle BFC=\angle BFD

but ∠BFC=45°

Therefore,

\angle DFC+45^\circ=125^\circ

\angle DFC=125^\circ-45^\circ

\angle DFC=80^\circ

Hence, The angle DFC is 80°

A function is given. h(t) = −t + 6/5 ; t = −3, t = 1
artcher [175]

Answer:

h(-3) = 4.2 or 21/5

h(1) = 0.2 or 1/5

Step-by-step explanation:

Plug in -3 for t.

-(-3) + 6/5 = 4.2 or 21/5

Plug in 1 for t.

-(1) + 6/5 = 0.2 or 1/5

Work out the length of the following rectangles
tiny-mole [99]

(a) a = 10.9 cm

(b) b = 20.78 cm

(c) c = 4.06 cm

<u>Explanation:</u>

(a)

height, h = 5cm

Hypotenuse, H = 12cm

Base, a = ?

Using pythagoras theorm:

(H)² = (h)² + (a)²

(12)² = (5)² + (a)²

119 = a²

a = 10.9 cm

(b)

Hypotenuse, H = 24 cm

Base, a = 12 cm

Height, b = ?

Using pythagoras theorm:

(H)² = (b)² + (a)²

(24)² = (b)² + (12)²

432 = b²

b = 20.78 cm

(c)

height, h = 4 cm

Hypotenuse, H = 5.7 cm

Base, c = ?

Using pythagoras theorm:

(H)² = (h)² + (c)²

(5.7)² = (4)² + (c)²

16.49 = c²

c = 4.06 cm

 PLEASE HELPPPPP ME PLEASE I DONT KNOW WHAT TO DO ☹️#7
nirvana33 [79]

Given:

The function is:

f(x)=-2x+5

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

f(x)=-2x+5

Step 1: Substitute f(x)=y .

y=-2x+5

Step 2: Interchange x and y.

x=-2y+5

Step 3: Isolate variable y.

2y=5-x

y=\dfrac{5-x}{2}

Step 4: Substitute y=g(x).

g(x)=\dfrac{5-x}{2}

Hence, the inverse of the given function is g(x)=\dfrac{5-x}{2} and the graphs of these functions are shown below.
