4. Maurice and his 3 friends with him.
Answer:
X=11
Step-by-step explanation:
2x+22=4(x+3)
2x-(22)=0
2x=22
x=22/2
x=11
Answer:
86°
Step-by-step explanation:
Given:
A = (6x + 10)°
B = (4x +30)°
Two angles are supplementary if they sum up to 180° ;
A + B = 180°
Now insert the parameters and solve;
6x + 10 + 4x +30 = 180
10x + 40 = 180
10x = 140
x = 14
So;
B = (4x +30)° = 4(14) + 30 = 86°
Answer:
the answer is the second one i think
Step-by-step explanation:
Step-by-step explanation:
The angles (8x + 28) and (4x - 7) are supplementary to each other so we can write
or
Also, note that the angle (4x - 7) and 
are vertical angles, which means that they are equal to each other. Therefore,
