What is the measure in degrees of angle EDF?

Mathematics
2 answers:
Gwar [14]3 years ago
8 0

Answer:

EDF = 20

Step-by-step explanation:

If the triangles are similar, the angle measurements have to be equal

<A = <D

<B = <E

<C = <F

Since BAC = 20,  <A = 20 that means D = 20

EDF = 20

Answer:

20 degrees.

Step-by-step explanation:

Since these triangles are similar, they will have congruent angles.

Since BAC is corrosponding to EDF, they will have the same angle measurment.

BAC = 20, so EDF = 20

A humpback whale swims at 40mph for 30 minutes, then rests for 15 minutes, then swims at 32 mph for 45 minutes. What is the whal
klasskru [66]
Average speed=totaldistance/ttoaltime

d=rt
40mph for 30mins (1/2 hr), travels 20mi
rest for 15min (1/4 hr), travels 0mi
swims at 32mph for 45min (3/4hr), travels 96/4=24mi

total distance=20+0+24=44
total time=1/2+1/4+3/4=1 and 1/2=3/2
44/(3/2)=44 times 2/3=88/3=29 and 1/3

about 29 and 1/3 mph

How do you find the percent of increase from 12 to 18?
olga nikolaevna [1]
Let's get the data out of the problem:

Nv = 18

Ov = 12

Now, we can apply in this equation that relates the new and the old values:

i = Nv / Ov

i = 18 / 12

i = 1.5

Now, we just consider what has passed from 1, and this is 0.5, converting to percentage it is:

p = 0.5 . 100

p = 50%

The increase was 50%.

Hope it helps.

A new company president is said to have caused the company "to do a 180." Before the new president, the company was losing 10,00
bezimeni [28]

Answer:

<u>Earning </u>10,000 per month.

Step-by-step explanation:

Since a "180" usually refers to an opposite, the opposite of "losing 10,000 per month" would happen.

So, the company would be <u>earning </u>money instead of losing money.

Solve for y in the following equation.
Tju [1.3M]

Answer:

y = \frac{z^2 - x}{2}

Step-by-step explanation:

Given:

\sqrt{x + 2y} = z

Required:

Solve for y (make y the subject of the formula)

SOLUTION:

\sqrt{x + 2y} = z

Square both sides

(\sqrt{x + 2y})^2 = z^2

x + 2y = z^2

Subtract both sides by x

2y = z^2 - x

Divide both sides by 2

y = \frac{z^2 - x}{2}
