Answer:
m<CGD = 26°
m<CGF = 100°
Step-by-step explanation:
m<CGD = 2x - 2
m<EGF = 37
m<CGF = 7x + 2
Since GE bisects <DGF, m<DGF = 2*m<EGF.
m<DGF = 2*37 = 74°
m<CGD + m<DGF = m<CGF (angle addition postulate)
(2x - 2) + (74) = (7x + 2)
Find the value of x using the equation above.
2x - 2 + 74 = 7x + 2
Collect like terms
2x + 72 = 7x + 2
-2 + 72 = 7x - 2x
70 = 5x
70/5 = 5x/5
14 = x
x = 14
m<CGD = 2x - 2
Plug in the value of x
m<CGD = 2(14) - 2 = 28 - 2
m<CGD = 26°
m<CGF = 7x + 2
m<CGF = 7(14) + 2 = 98 + 2
m<CGF = 100°
V + f = a + 2
15 + f = 24 + 2
f = 26 - 15
f = 11 (11 faces)
height = 43 m
d = 14m
r = 7 m
A = π.r.g
g² = r²+h²
g² = 7²+43²
g² = 1898
g = \/1898
g ~ 43,56 m
A = π.r.g
A = π.7.43,56
A = 304,92 π
A = 304,92*3,14
A = 957,45 m² (área lateral)
The answer is actually $17.821. I just took the test.
Answer:
v=7
Step-by-step explanation:
add 15 to both sides 5v-15+15=20+15
simplify
5v=35
divide both sides by 5
5v/5 = 35/5
and you get 7
hope this helps you
F(r) = 60 - 2/3r r = 12
Substitute r for 12
f(12) = 60 - 2/3(12) 12 * 2/3 = 8
f(12) = 60 - 8
f(12) = <u /><em><u>52</u></em><em><u /></em>
52 is your answer
