Answer:
x = 18
Step-by-step explanation:
The angle vertically opposite (5x + 2) is also (5x + 2), then
(5x + 2) and (5x - 2) are same- side interior angles and sum to 180° , that is
5x + 2 + 5x - 2 = 180
10x = 180 ( divide both sides by 10 )
x = 18
Answer:
4.674 × 10²
Step-by-step explanation:
7.4 x 10° + 4.6 x 10²
Note : 10° = 1 . Any number raise to power zero is 1
7.4 × 1 + 4.6 × 100
7.4 + 460
= 467.4
= 4.674 × 10²
