Answer:
∠ SPQ = 75°
Step-by-step explanation:
The sum of the 4 angles in a quadrilateral = 360°
Subtract the sum of the 3 angles from 360 for ∠ SPQ
∠ SPQ = 360° - (90 + 74 + 121)° = 360° - 285° = 75°
Answer:
143 degrees
Step-by-step explanation:
First find angle ACB which is 180-83=97
Then angle ABC which is 180-134=46
Then angle CAB (97+46)-180=37
Finally angle HAB 180-37=143
Answer:
67 mph
Step-by-step explanation:
Well the average speed is miles per hour so simply its 301.5 miles and 4.5 hours
which to see how many miles in one hour:
301.5/4.5 = 67
5+2i. You only have to change the operation of the original expression, not the signs (positives and negatives) of each term.
It is 10
