The answer is 138
Because the angle is 180 and what I did was 2 x 21 = 42 and I did 180-42 equals to 138
is this like Algebra 1 or 2? you can try to use a graph generator to help
Answer:
a=2, b=-20
Step-by-step explanation:
4(2xsquared -5x+3)= 8xsquared -20x +12
Answer:
45*
Step-by-step explanation:
180-115=65
65=angle 2
180-110=70
70=angle 1
70+65=135
180-135=45
45=angle 7
angle 7 and 6 are vertical angles so angle 6=45
angle 6 and angle 5 are an example of alternate interior angles soo
angle 5=45*
Hope I helped!
