Answer:
D. 93
Step-by-step explanation:
Given:
m<1 = 28°
m<6 = 65°
m<5 = 65°
Required:
m<MAX
Solution:
m<MAX = m<1 + m<5 (angle addition postulate)
Substitute
m<MAX = 28° + 65°
m<MAX = 93°

Answer:
C 4x -2y = 1
Step-by-step explanation:
The y-intercept of the offered choices can be found by dividing the constant by the y-coefficient.
A: not in standard form (coefficients are not integers)
B: 2/-5 = -2/5 . . . not -1/2
C: 1/-2 = -1/2 . . . a good candidate
D: 1/-1 = -1 . . . not -1/2
Answer:
c
Step-by-step explanation:
Since the polyhedron is about 78.5 m², the radius of the sphere is 2.5 m
Since the sum of the faces of the polyhefron equals the surface area of the sphere, we find its surface area.
<h3>What is the surface area of sphere?</h3>
The surface area of sphere is given by A = 4πr² where r = radius of sphere
<h3>Radius of the sphere</h3>
Making r subject of the formula, we have
r = √(A/4π)
Given that he sum of all the faces of the polyhedron is about 78.5 square meters, this is equal to the surface area of the sphere.
So, A = 78.5 m²
Substituting this into the equation for r, we have
r = √(A/4π)
r = √(78.5 m²/4π)
r = √(19.625 m²/π)
= √(6.246 m²)
= 2.499 m
≅ 2.5 m
So, the radius of the sphere is 2.5 m
