If the equation is 4x+1/3=20, your answer would be x=59/12.
- You would subtract 1/3 from each side. (1/3 - 1/3) (20-1/3)
- Then your new equation would be 4x = 59/3
- You would divide 4 from each side (4/4) (59/3 / 4)
- x = 59/12
The measure of the fourth interior angle in the quadrilateral is 145
Answer:
Step-by-step explanation:
question no 3
In complementary angles , sum of two angles is 90 degree. so here,
angle A + angle B = 90 degree
angle A is given i.e 11 degree . substitute the value of A
11 degree + angle B= 90 degree
angle B = (90 -11) degree
angle B = 79 degree
question no 4
In supplementary angles , sum of two angles is 180 degree so here,
angle A + angle B = 180 degree
angle A is given i.e 149 degree . substitute the value of angle A
149 degree + angle B = 180 degree
angle B = (180 - 149) degree
angle B = 31 degree
the answer is c

Answer:
(-30, 10)
Step-by-step explanation:
if you multiply both -20 and 60 by -0.5 you get 10 and -30 respectively. being the only pair of numbers achievable by the proportion property.
