Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
Angles 1 and 5 are corresponding angles.
If angles 1 and 5 are congruent, then the lines are parallel.
This means the measurement of angle 1 needs to equal the measurement of angle 5.
This is the equation we must solve:
3x+10=4x+2
Subtract 3x on both sides:
10=1x+2
Subtract 2 on both sides:
8=1x
Use multiplicative identity property:
8=x
So if x=8, then the angles 1 and 5 which are corresponding are congruent.
If corresponding angles are congruent, then the lines are parallel.
Twice 2 to the 30-th power is
2*2³⁰ = 2¹*2³⁰ = 2³¹
For very large numbers, it is the usual practice to use scientific notation.
From the calculator, obtain
2³¹ = 2.1475 x 10⁹
Answer: 2.1475 x 10⁹
