Triangle angle - sum theorem what is the value of y?

dangina [55]

Answer:

y = 5

Step-by-step explanation:

All angle measures in a triangle add up to 180°.

This means that 63 + 82 + 7y = 180

Solving for Y:

Step 1: Combine like terms.

$(7y) + (63+82)=180$
$7y + 145 = 180$

Step 2: Subtract 145 from both sides.

$7y + 145 - 145 = 180 - 145$
$7y = 35$

Step 3: Divide both sides by 7.

$\frac{7y}{7} = \frac{35}{7}$
$y = 5$

Step 4: Check if solution is correct.

$7(5) + 63 + 82 = 180$
$35 + 63 + 82 = 180$
$98 + 82 = 180$
$180 = 180$

Therefore, y = 5.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Find the arc length for a circle with diameter 10 inches and central angle 60 degrees. Round to the nearest tenth.

UkoKoshka [18]

Answer:

C. 5.2 cm

Step-by-step explanation:

Arc length formula:

$s = \dfrac{n}{360^\circ} 2 \pi r$

where s = arc length

n = central angle of arc

r = radius of circle

diamter = d = 10 cm

r = d/2 = 10 cm/2 = 5 cm

n = 60 deg

$s = \dfrac{n}{360^\circ} 2 \pi r$

$s = \dfrac{60^\circ}{360^\circ} 2 \times 3.14159 \times 5 ~cm$

$s = 5.2~cm$

Answer: 5.2 cm

Tommy is using a bucket to collect nuts from a nut tree. He then dumps the bucket into a barrel for shipping of the nuts. He not

NISA [10]

Answer:

3/8 bucket

Step-by-step explanation:

Given that 1/4 bucket of nuts fills 2/3 of the barrel

PART A

To find the amount of nuts that fills entire basket we can put this as:

1/4 bucket → 2/3 barrel
x bucket → 1 barrel

Use cross-multiplication to find the value of x:

x×2/3 = 1×1/4
x = 1/4 ÷ 2/3
x = 1/4×3/2
x = 3/8 bucket

PART B

Using the bucket to barrel ratio to solve the problem. Having the number of required buckets as x and considering full barrel as 1 helps to find the value of x.
