Answer:
A) m∠3 + m∠4 = 180
Step-by-step explanation:
Both angles make a straight line which has an angle of 180.
Multiply 84 times 2 to find it hopes this helps.
27k -6 is equal to 3(9k - 2 )
and 5x +60 is equal to 5(x + 12) :)))
i hope this is helpful
have a nice day
Answer:
4
Step-by-step explanation:
the third angle of the inner triangle is defined by using the rule that the sum of all angles in a triangle must be 180 degrees. let's call this angle a
180 = 48 + 16x + a
132 - 16x = a
and then we know that both angles, 28x and a together must also be 180, as they are complementing each other to cover the whole top of the base line.
so,
28x + 132 - 16x = 180
12x = 48
x = 4
Start at -4 and go over to the right 6. - is left and +is right. the answer is 2.
