Because the 2 sides of the triangle are the same, they are both 21, the two bottom angles would also be the same.
The 3 inside angles of a triangle must equal 180 degrees.
The top angle is given as 38, so the remaining two angles must equal 180 - 38 = 142 degrees.
Since the 2 bottom angles would be the same, divide 142 by 2 to get x.
X = 142 / 2 = 71 degrees.
Answer:
32 years old
Step-by-step explanation:
Reverse what the teacher said. Half 120 to get 60. Subtract 28 from 60. The teacher is 32.
Step-by-step explanation:
To find unit rate
1 bag = 36÷ 3 = 12
So unit rate = $12
Answer:True
Step-by-step explanation:
Average speed refers to the total distance covered in a specific time . it also a scalar quantity (has magnitude but no direction)
Average speed=distance / time
-Speed is in kilometers/hours or meter/seconds
-distance is in kilometers or meters
-time is in hours or seconds
