Answer:
x=126 degrees
Step-by-step explanation:
x+21=147 because they are opposite adjacent angles
x=126 degrees
57 - 4t > = 13.....subtract 57 from both sides
-4t > = 13 - 57
-4t > = - 44 ...divide both sides by -4, and change the inequality sign
t < = -44 / -4
t < = 11
u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.
Answer:
42 degrees, and 48 degrees
Step-by-step explanation:
set up an equation to find x, the first angle measure
(x+6)+x=90
then simplify:
2x+6=90
2x=84
x=42
So, the first angle measure is 42, now to find the second angle measure, add 6 to 42, and you will get 48.
