Given that the sum of the three interior angles of a triangle is equal to 180°, we can formulate the following equation:
2x + 1 + 2x + 93 = 180
4x + 94 = 180 (Adding like terms)
4x = 180 - 94 (Subtracting 94 from both sides of the equation)
4x = 86
x= 86/4 (Dividing by 4 on both sides of the equation)
x= 21.5
Replacing in the angles we have:
Angle 2x + 1 ---> 2(21.5) + 1= 44
Angle 2x ---> 2(21.5) = 43
The angles of the triangle are 43, 44 and 93.
Answer:
0
Step-by-step explanation:
Simplifying
x2 + -4x + -12 = 0
Reorder the terms:
-12 + -4x + x2 = 0
Solving
-12 + -4x + x2 = 0
Solving for variable 'x'.
Factor a trinomial.
(-2 + -1x)(6 + -1x) = 0

Answer:
The number of student numbers that are possible = 729,000,000 student numbers
Step-by-step explanation:
The number of possible numbers that can take the place of the first two digits = 9 possible numbers each
The number of possible numbers that can take the place of the 3rd to the 9th digits = 10 possible numbers each
The number of possible numbers that can take the place of the 10th digits = 9 possible numbers each
The total number of possible numbers is given as follows;
9 × 9 × 10⁶ × 9 = 729000000 possible student numbers
