Answer:
The angles are complementary
x is 55 degrees
Step-by-step explanation:
Complementary angles are angles that sums up to 90 degrees
Since a ray intersects two other rays forming a right angle, hence the sum of the two angles is 90degrees and this shows that the angles are complementary.
Given the two angles to be x and (x-20). Taking their sum and equating it to 90 degrees, we will have;
x + x - 20 = 90
2x - 20 = 90
2x = 90+20
2x = 110
x = 110/2
x = 55 degrees
Hence the value of x is 55degrees
AREA OF A SECTOR =1/2(Ф.R²). Note that R = Diameter/2
AREA OF A SECTOR =1/2(170°).(9.1)/2) =386.75 cm²
Answer:
g = 1/2
Step-by-step explanation:
4 is the product of 8 and g.
=> 8*g = 4
=> g = 1/2
