The answer would be 240 because 12 times 8 equals 96 and 18 times 8 equals 144 but you have to add it so the answer is 240

Two angles of a triangle have the same measure and the third one is 18 degrees greater than the measure of each of the other two
kvv77 [185]

Answer:

72°

Step-by-step explanation:

Let the 2 equal angles be x then the third angle is x + 18

The sum of the 3 angles in a triangle = 180°, thus

x + x + x + 18 = 180, that is

3x + 18 = 180 ( subtract 18 from both sides )

3x = 162 ( divide both sides by 3 )

x = 54

Hence

the largest angle = x + 18 = 54 + 18 = 72°

find the radian measure of the centeral angle of a circle of radius r and arc length of s. a. R=22 ft and s=10ft
Harman [31]

Answer:

\theta=0.45rad

Step-by-step explanation:

The radian measure of the centeral angle of a circle of radius r and arc length of s, can be calculated using the relation: s=r\theta

The radius is given as r=22ft and the arc length is given as: s=10ft

Let us substitute the values into the formula and solve for \theta.

This implies that:

10=22\theta

We divide both sides by 22

\frac{10}{22}=\theta

Therefore \theta=\frac{5}{11}

Systems of 3 equations by using a combination of both substitution and elimination
LiRa [457]
X-2y+z=3
2x+y-2z=31
-x+2y+3z=-23
multiply the first equation by -2 and add the results to the second equation:
x-2y+z=3
+5y-4z=25
-x+2y+3z=-23
multiply the first equation by 1 and the results to the third equation:
 x-2y+z=3
5y-4z=25
4z=-20
solve for z:
4z=-20
z=-5
solve for y:
5y-4z=25,z=-5
5y-(4*-5)=25
5y+20=25
5y+20-20=25-20
5y=5
y=1
solve for x by substituted y and z into the first equation:
x-2y+z=3, y=1, z=-5
x-(2*1)-5=3
x-2-5=3
x-7=3
x-7+7=3+7
x=10
the answer are x=10, y=1, z=-5
