Answer:
A = 60
B = 55
C = 65
Step-by-step explanation:
The sum of the angles of a triangle is 180
A + B+C = 180
x+ x-5 + 65 = 180
Combine like terms
2x+60 =180
Subtract 60 from each side
2x= 180-60
2x= 120
Divide by 2
2x/2 = 120/2
x= 60
A = 60
B = 60-5= 55
C = 65
Answer:
C; D; E
Step-by-step explanation:
✔️Angles in a straight line = 180°
Therefore, m<5 + m<6 = 180° is correct.
✔️Exterior angle of a triangle = the sum of the opposite interior angels based on the exterior angle theorem of a triangle.
Therefore,
m<2 + m<3 = m<6 is correct.
✔️The sum of m<2 + m<3 + m<5 = 180° is correct. This is true based on the sum of triangle theorem.
Answer:
A1 = 18
A(n) = A (n-1) -2
Step-by-step explanation:
N represents the number in a sequence and the difference in the sequence is -2 since each time the number is listed in the sequence it is divide by 2.
Answer:
a) (4,-2) b) (77,77)
Step-by-step explanation:
Times the brackets out and then add them or take them away
Answer:
Step-by-step explanation:
First, distribute the 2 to the 3z and -6 within the parenthesis.
You know have 6z -12/5 + 6 = 10
Subtract 6 from both sides of the equation
6z -12/5 = 4
Multiply 5 on both sides of the equation
6z -12 = 20
Add 12 to both sides of the equation
6z = 32
Divide by 6 on both sides of the equation
z = 32/6
Simplify
z = 16/3
I hope that this helps! :)
