we are given
The angle is at right angled
It means that it's angle will be 90 degree
Since, these angles are part of right angle
so, their sum must be 90 degree
so, we get
now, we can solve for a
divide both sides by 7
and we get
.............Answer
Answer:
7

Answer:
40
Step-by-step explanation:
area= length times width
1 times 10= 10 times 2= 20
2 times 10=20
20+20=40
Answer:
214°
Step-by-step explanation:
Full circle measure = 360°
Measure of arc AB = 146° (central angle has the same measure as measure of intercepted arc)
Therefore:
Measure of arc ACB = 360° - arc AB
Measure of arc ACB = 360° - 146°
= 214°
