Answer:
22°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + x + 136° = 180°
2x + 136° = 180° ( subtract 136° from both sides )
2x = 44° ( divide both sides by 2 )
x = 22°
Answer:
The variable y is eliminated.
Step-by-step explanation:
To add a system of equations, we add the common terms. x with x, y with y and values with values.
In this question:
5x + 6y = 32
5x – 6y = 8
Adding:
5x + 5x + 6y - 6y = 32 + 8
10x = 40
So the variable y is eliminated.
Step-by-step explanation:
answer is d and b.
they both lie in same line
Answer:
180-32= 148°
Step-by-step explanation:
DPC is a straight line that means that it is 180°.
DPB is 32°.
So we just take DPB out of DPC.
180-32= 148°
