Answer:
x = 28
m<ABC = 57°
Step-by-step explanation:
✔️(2x + 1)° + 33° = 90° (complementary angles)
Solve for x
2x + 1 + 33 = 90
Add like terms
2x + 34 = 90
2x = 90 - 34 (subtraction property of equality)
2x = 56
Divide both sides by 2
x = 28
✔️m<ABC = 2x + 1
Plug in the value of x
m<ABC = 2(28) + 1
= 56 + 1
m<ABC = 57°
7 : 21
which can be simplified to 1 : 3 as both sides are divisible by 7
The circle is closed when it is = and open when it is not = to the number that is being circled.
Answer:
4x - 3 = 25
+ 3 + 3
4x = 28
x = 7
<em>1st = add like terms</em>
<em>2nd = simplify</em>
<em>3rd = divide both sides</em>
