Answer:
x = 10°
Step-by-step explanation:
8x + 50 = 130 (corresponding angles are equal)
8x = 80
x = 10°
1) 3/12
Because 1/3 would have changed to 4/12,
1x4= 4
3x4=12
You need to multiply them by the same number and 1) was multiplied by three on the numerator and four on the denominator.
A+c = 150
10.25a+7.75c = 1470
Looks like a good question, using the mathematical term of "radical."
