Answer:
2π m.
Step-by-step explanation:
Arc XY is 1/4 of the circumference of the circle
= 1/4 * 2π * r
= 1/2 π * 4
= 2π m.
Answer:
a^3 +r^2
Step-by-step explanation:
a is multiplied three times so it goes to a^3
r is multiplied twice so it goes to r^2
Answer:
x=16
Step-by-step explanation:
2(x/8)=2
2x / 16=2
x 16 x 16
2x=32
2x/2= 32/2
x= 16
Answer:
36°
Step-by-step explanation:
134° is the exterior angle of the triangle.
By the exterior angle theorm
134° = 98° + y
y = 134° - 98° = 36°
Following the principle of supplements angles, the angle next to the 101 is 79°. 79+38+c(call the third angle c) = 180
c = 180-117 =63° x is supplemental to c so 180 = x +c
180=x + 63
x =117
