Goryan [66]

Step-by-step explanation:

a) 1.16× 10^-6

standard form should be less than 10. therefore, count decimal places from where the decimal point is located to the right until you reach a number less than 10 ....count the number of shifts in the above is 6 shifts to the right. when moving to the right, power will be negative.(-6)

1.157/1.16 ×10^-6

b) 6.79 × 10^10

67890000000....count till a number less than 10.there will be 10 shifts to the left. the 10 will be your power,(positive) since u r moving to the left exponent is positive

Select the correct answer. Two exterior angles of a triangle measure 135° and 100°. What are the measures of the interior angles
ozzi

Answer:

C

Step-by-step explanation:

interior angle + exterior angle are supplementary

interior angle = 180° - exterior angle

⇒ interior angle = 180° - 135° = 45°

and interior angle = 180° - 100° = 80°

The sum of the 3 angles in a triangle = 180°

To find the third interior angle, subtract the sum of the 2 interior angles from 180

third interior angle = 180° - (45 + 80 )° = 180° - 125° = 55°

interior angles are 45°, 55° and 80°
