Answer:

x = 14.7

Step-by-step explanation:

Using the sine rule

\frac{a}{sin(A)}  = \frac{b}{sin(B)}  = \frac{c}{sin(C)}

Substitute the given values.

\frac{7}{sin(20)}  = \frac{x}{sin(46)}

Rearrange the equation to get x on it's own.

\frac{7sin(46)}{sin(20)}  = x

x = 14.72246211

x = 14.7 (1dp)

I am not sure if I am right, but this is the best I can answer.


Useing reason, and logic, my guess would be if you take 125, and divided it by 4, you would get 31.25. that should be the answer... if i am wrong, i am truely sorry. I havent been in the subject in a while...

Vasco needs to know the area of the four-pointed star
Rama09 [41]

Answer:

Step-by-step explanation:

Find the area of the base

The base is a square.

The formula is Area = s^2

s = 1.5

Area = 1.5^2

Area = 2.25 sq cm.

Area of 1 triangle

h = 2.4

b = 1.5

Area = 1/2 * b * h

Area = 1/2 * 1.5 * 2.4

Area = 1.8 cm^2

Area of 4 triangles

Area = 4 * area of 1 triangle

Area = 4 * 1.8

Area = 7.2

Total Area = 2.25 + 7.2 = 9.45 cm^2

Calculate the distance between the points M=(-1,-1) and P=(2, -8) in the coordinate plane. Give an exact answer (not a decimal a
pantera1 [17]
This is a Pythagorean Theorem problem. 3^2 + 7^2 = 58. C^2 = 58. C = 7.6157 (exact)

There is no exact answer for this. The closest we can get to 58 is 7.6157, which would leave us at 57.9988. So the approximate value is 7.6, but if you need the closest answer, it’s 7.6157.

Find the slope of the line that contains the points (7, 3) and (7, 9). Round to 2 decimal places.
Lunna [17]

answer = not define

Step-by-step explanation:

slope = (y2- y1) / (x2- x1)

= 9-3 / 7-7

= 6/0

= not define

I think points are wrong
