Write An Equation That Can Be Used To Find The Degree Measure Of Angle BDont Put Links !

Answers

Answer 1

Answer:

Because they are supplementary angles, their sum is 180°.

∠b = 180° - 81°

∠b = 99°

Answer 2

Answer:

[tex]180-81=b[/tex]

Step-by-step explanation:

Supplementary angles are angles that add up to 180. Normally, they are supplementary because they lie adjacent to one another on a line.

In this base, b is supplementary to 81! Meaning, to find b we can simply subtract 81 from 180.

6) On Saturday afternoon tickets
for a popular band were put on sale
on the internet. There are 900
tickets and every hour about 75
tickets are sold. How long will it
take for there to be only 150 tickets
left?

Answers

Answer:

It will take 10 hours

Step-by-step explanation:

first you subtract 150 from 900 (900-150) to get 750. next you divide 750 by 75 since that is the rate the tickets are being sold (750÷75) which would equal to 10.

Step-by-step explanation:

Two times a umber j is expressed as 2j

if Fifty-seven is more than two times j", this means we will have to add 57 to 2j as shown;

f(j) = 2j + 57

What is the approximate area of the shaded sector ?

Answers

Answer:

7.5 cm²

Step-by-step explanation:

Area of shaded sector = θ/360 × πr²

Where,

θ = 180° - 84° = 96°

r = ½(6) = 3 cm

Area of shaded sector = 96/360 × π × 3²

Area = 7.53982238 ≈ 7.5 cm²

What is the value of x?

Answers

Answer:

The value of x=12

because the whole thing is 90 and the other angles are equal to 78 if you add them together. So you would subtract 90-78 which equals 12.

In ARST, the measure of ZT=90°, the measure of ZR=39°, and TR = 55 feet. Find the

Answers

Answer:

44.5 ft

Step-by-step explanation:

Reference angle = 39°

Opposite = x

Adjacent = 55

Apply trigonometric function TOA:

Tan 39 = Opp/Adj

Tan 39 = x/55

55 × Tan 39 = x

44.5381218 = x

x ≈ 44.5 ft

What are the solution(s) to the quadratic equation 40 - x2 = 0?
O x = +2/10
O x = +4/10
O x = +2/5
x = +4V5

Answers

Answer:

±2sqrt(10)

Step-by-step explanation:

40 - x^2 = 0

Add x^2 to each side

40 -x^2 + x^2 = x^2

40 =x^2

Take the square root of each side

±sqrt(40) =sqrt(x^2)

±sqrt(4)sqrt(10) =x

±2sqrt(10) =x

Ahamd wants to cover a box that is 6 cm long 4 cm high and 4 cm wide with material on all the sides how much material does he need



​

Answers

Answer:

56cm²

Explanation:

the amount of material he needs would be the total surface area of the box. surface area can be calculated by finding the sum of surface area of all the sides of the box. since the opposite sides are equal, we can find the surface area of 3 different sides and then multiply it by 2.

(4 + 4) + (4 + 6) + (6 + 4) × 2

= 8 + 10 + 10 × 2

= 28 × 2

= 56cm²
