Answer:
π4;3π4
Step-by-step explanation: Trig table gives:
sinx=√22 --> arc x=π4
Unit circle gives another arc x that has the same sin value:
x=π−π4=3π4
Answer:
x = 2, y = 3
Step-by-step explanation:
x - 3y = - 7 → (1)
x = 5 - y → (2)
Substitute x = 5 - y into (1)
5 - y - 3y = - 7
5 - 4y = - 7 ( subtract 5 from both sides )
- 4y = - 12 ( divide both sides by - 4 )
y = 3
Substitute y = 3 into (2)
x = 5 - 3 = 2
solution is (2, 3 )
Actually Welcome to the concept of Surface Areas and Volume.
==> Volume of Cylinder = πr^2h
==> 27π = πr^2(3)
==> 27 = r^2 (3)
==> r^2 = 9
==> r = 3 inch
hence the radius is 3 inches.
Step-by-step explanation:
in triangle ABC, BM has divided the triangle into 2 equal parts triangle ABM and CMB, AM and CM are two equal lines
AM=CM (they are line segments not angles)
angle BAM=angle BCM
angle ABM=angle BCM
angle AMB=angle CMB
therefore, triangles AMB and CMB are congruent
