Answer:

Problem:

180-144=36

36/2=18

A=18

Step-by-step explanation:

The full area of half of a circle is equal to 180 degrees. To find the missing value of both A's you must take the full degrees of 180 and subtract 144 from 180. Next you have to take the remaining number and divide it by two because both of the missing value's are equivalent.

Answer:

x = 9

Step-by-step explanation:

First equation = 4x - 8

Second equation = 7x - 35

Seperate the equation with an equal sign to make it an equality equation and solve for X so :

4x - 8 = 7x - 35 (Given)

-3x - 8 = -35 (Subtraction property of equality)

-3x = -27 (Addition property of equality)

x = 9 (Division property of equality)

Solution:

x = 9

Use the Law of Sines to find the missing angle of the triangle. Find m<b to the nearest tenth.
defon
1. By the Law of Sines, you have:

 SinA/a=SinB/b=SinC/c

  2. You don't need the fraction SinC/c, so you can eliminate it. Then:

 SinA/a=SinB/b

 A=40°
 a=19
 B=m∠b
 b=13

 3. When you substitute this values into SinA/a=SinB/b, you obtain:

 SinA/a=SinB/b
 Sin(40°)/19=SinB/13
 SinB=13xSin(40°)/19
 m∠b=SinB^-1(13xSin(40°)/19)
 m∠b=26.1°

 Therefore, the answer is: 26.1 degrees.

Solve the equation. 3 (x - 1) = 18
In-s [12.5K]
  • 3 ( x - 1 ) = 18
  • or, 3x - 3 = 18
  • or, 3x = 18 - 3
  • or, 3x = 15
  • or, x = 15 ÷ 3
  • or, x = 5

<u>Answer</u><u>:</u>

<u>x </u><u>=</u><u> </u><u>5</u>

Hope you could understand.
