A circle is centered at the vertex of an angle, and the angle's rays subtend an arc that is 74.46 cm long. 1/360th of the circumference of the circle is 0.51 cm long. What is the measure of this angle in degrees?
 ________degrees
​

Answers

Answer 1

Answer:

146°

Step-by-step explanation:

You're given an angle, where the vertex is the center of a circle. This makes the angle's rays two radii of the circle. You are then given the length of 1/360th of the circle, which is .51cm, which is also 1 degree of the circle.

If the arc of the circle between the angle's rays is 74.46 cm. It becomes a division problem:

[tex]\frac{74.46 cm}{.51 cm}[/tex]

After the division, the fraction simplifies to 146, which is 146 segments of .51cm in the arc, and since .51cm is equivalent to 1 degree of the circle, the arc is 146 degrees.

Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units. The larger triangle's longest side is 52 units. What is the perimeter of the larger triangle? first o answer get brainliest

Answers

Answer:

117

Step-by-step explanation:

So basically, how I figured it out is 20-15 is 1/4 of 20. So I had to find the 1/4 of 52 which is 13.  But 15 is 3/4 of 20 so then you multiply 13 times 3 which is 39.

10 is half of 20. So you find half of 52. Which is 26.

52+39+26 is your equation.

Which adds up to 117. So 117 is your answer

I used 20 because in the smaller triangle 20 was the largest side like 52 in the biggest triangle.

k/3 + 4=10

Answers

K/3 + 4 = 10
K/3 = 10 - 4
K/3 = 6
K = 6x3
K = 18

Answer:

k=18

Step-by-step explanation:

k/3+4=10

subtract 4 from both sides.

k/3+(4-4)=10-4

k/3=6

multiply 3 on both sides.

k/(3/3)=6*3

k=18

Check using substitution method.

(18)/3+4=10

Use order of operations to solve. (PEMDAS)

Answer:

Part A:  y = 4.5x + 22

Part B:  31 inches

Step-by-step explanation:

Part A:

the y-intercept appear to be at 22

the slope can be found by using the points (0, 22) and (4, 39)

m = 39 - 22

        4 - 0

m = 17 / 4 = 4.3 and this is close to 4.5

Part B:

plug in 2 for 'x' in the equation: y = 4.5x + 22

y = 4.5(2) + 22

y = 9 + 22

y = 31

If ON = 9x - 8, LM = 8x + 4, NM = x - 8, and OL = 3y - 5, find the values of x and y for which LMNO must be a parallelogram.​

Answers

Answer:

x is 12 and y is 3

Step-by-step explanation:

Given a parallelogram LMNO,

LM = ON and OL = NM

Given;

ON = 9x - 8

LM = 8x + 4

NM = x - 8, and

OL = 3y - 5

Substitute into the expression

LM = ON

8x + 4 = 9x - 8

8x - 9x  = -8 - 4

-x  = -12

x = 12

Also OL = NM

3y - 5 = x - 8

3y - 5 = 12-8

3y - 5 = 4

3y = 4+5

3y = 9

y = 9/3

y = 3

Hence the value of x is 12 and y is 3
