Answer:
80
Step-by-step explanation:
< 2 + < 3 + 90 = 180
< 2 = x + 8
< 3 = 2x + 7
x + 8 + 2x + 7 + 90 = 180
3x + 105 = 180
3x = 180 - 105
3x = 75
x = 75/3
x = 25
< 2 = x + 8 = 25 + 8 = 33 <==== answer is D
< 3 = 2x + 7 = 2(25) + 7 = 50 + 7 = 57
Answer: Hello, To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
Acute. 90 degrees is a right angle, 180 degrees is a straight angle, obtuse angles are greater than 90 degrees, while acute are less than 90 degrees.
Answer:
igure it out based on the explanation
