Answer:
∠A= 80°
Step-by-step explanation:
if they are supplementary then put them equal to 180
7x + 3 +7x + 23 = 180
14x + 26 = 180
14x = 154
x= 11
now plug in
7(11)+3
77+3= 80
Answer:
1 2/5
Step-by-step explanation:
1 3/5 = 8/5, 7/8 * 8/5 = 1.4
1.4 as a fraction is 7/5
Simplify it and you get 1 2/5
Answer:
A straight horizontal line ranging from -3 to 1
Step-by-step explanation:
Draw a cartesian plane. Plot (0,-3) and (1,0)
First plotting: x = 0, y = -3
Second plotting: x = 1, y = 0
The plotting gives a straight horizontal line (drawn from left to right)
Answer:
d = 85
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
d = 180 - 95 = 85
