What is the measure of def 78° PLEASE HELP

Mathematics
1 answer:
Scorpion4ik [409]3 years ago
7 0

Answer:

The measure of arc DEF is 204°

B is correct

Step-by-step explanation:

In a circle center at O.

∠DOF and ∠DEF are lie on same base but ∠DOF at center and ∠DEF on circle.

Thus, ∠DOF = 2 ∠DEF

minor ∠DOF = 2 x 78 = 156°

We need to find arc DEF.

DEF is central angle of major∠DOF

major∠DOF + minor ∠DOF = 360°     (Complete angle at center)

            major∠DOF  +  156° = 360°

                         major∠DOF = 204°

major∠DOF is arc DEF.

Hence, The measure of arc DEF is 204°

What decimal is equivalent to 4/5 + 0.05
UNO [17]
To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:- 

4/5 
4 ÷ 5 = 0.8

Now lets substitute 0.8 for 4/5 and then add.

4/5 + 0.05
0.8 + 0.05 = 0.85

CHECK OUR WORK:-

0.85 - 0.8 = 0.05
We were RIGHT!!

So, the decimal 0.85 is equivalent to 4/5 + 0.05.

Hope I helped ya!! xD

if a tree casts an 8 meter shadow, and the angle from the ground to the tree is 30 degrees, what is the approximate height of th
Virty [35]
Using SohCahToa, we can find the height of the tree. Let the tree height be h. 8m is adjacent to the 30° angle.
\tan(30)  =  \frac{h}{8}  \\ h = 8 \tan(30)  \\ h = 4.62
The answer is A) 4.6 m

horace is a professional hair stylist. let ccc represent the number of child haircuts and aaa represent the number of adult hair
Novay_Z [31]

He can give at most 2 adult haircuts with the remaining time

<h3>How many adult haircuts at most can he give with the remaining time? </h3>

The inequality is given as:

0.75C + 1.25A <= 7

Also, we have

C = 5

Substitute C = 5 in 0.75C + 1.25A <= 7

0.75 * 5 + 1.25A <= 7

Evaluate the product

3.75 + 1.25A <= 7

Evaluate the like terms

1.25A <= 3.25

Divide by 1.25

A <= 2.6

Rewrite as

A < 3

Hence, he can give at most 2 adult haircuts with the remaining time
