Answer:
X=107°
Step-by-step explanation:
180-73=107
this is to get the angle on the opposite side of the 73.
corresponding angles are similar hence angle x is 107°
Answer:
x = 50
Step-by-step explanation:
The two angles are vertical angles, so they are congruent. Congruent angles have equal measures. Set the angle measures equal to each other, and solve the equation for x.
2(x + 10) = 3x - 30
Distribute on the left side.
2x + 20 = 3x - 30
Subtract 2x from both sides.
20 = x - 30
Add 30 to both sides.
50 = x
x = 50
Answer:
18
Step-by-step explanation:
4(3)=12
12+6=18
Answer:
Option (c) is correct.
Add a constant to a row does not involves while solving a system of equations using matrix.
Step-by-step explanation:
Given : solving a system of equations.
W have to choose from given options that can not be used on a matrix when solving a system of equations.
Since solving the system using matrix method involve
1) adding of rows,
2) multiplying a row by a constant.
3) interchange rows
But add a constant to a row does not involves while solving a system of equations using matrix.
Thus, Option (c) is correct.
The answer for this proportion is 50.
156.25 times 16 =2,500
2,500 divided by 50=50
X=50
