Answer:
Step-by-step explanation:
Number of side = n = 7
Sum of interior angles of 'n' sided polygon = (n - 2) *180
= (7 - 2)* 180
= 5 * 180
= 900
x + 150 + x -20 + 140 + 120 + x + 20 + 130 = 900
Combine like terms
x +x +x + 150 - 20 + 140 + 120 + 20 +130 = 900
3x + 540 = 900 {Subtract 540 from both sides}
3x = 900 - 540
3x = 360 {Divide both sides by 3}
x = 360/3
x = 120
Interior angle Exterior angle
∠A = 120 180 - 120 = 60
∠B = 130 180 - 130 = 50
∠C = 120 + 20 = 140 180 - 140 = 40
∠D = 120 180 - 120 = 60
∠E = 140 180 - 140 = 40
∠F = 120 - 20 = 100 180 -100 = 80
∠G = 150 180 - 150 = 30
Answer:
D. 70°
Step-by-step explanation:
Given:
m<DGB = 35°
m<CGF = 75°
Required:
m<AGE
SOLUTION:
m<EGD = m<CGF (vertical angles are congruent)
m<EGD = 75°
m<AGE + m<EGD + m<DGB = 180° (angles on a straight line)
m<AGE + 75° + 35° = 180° (substitution)
m<AGE + 110° = 180°
Subtract 110 from each side of the equation
m<AGE = 180° - 110°
m<AGE = 70°

Answer:
1:10
Step-by-step explanation:
the ratio we can it is
![\frac{amount\:salt}{amount\:sugar}\\\\\frac{\frac{1}{4}}{2\frac{1}{2}}\\\\\frac{\frac{1}{4}}{\frac{5}{2}}\\\\\frac{1\times2}{4\times5}\\\\\frac{1}{2\times5}\\\\\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7Bamount%5C%3Asalt%7D%7Bamount%5C%3Asugar%7D%5C%5C%5C%5C%5Cfrac%7B%5Cfrac%7B1%7D%7B4%7D%7D%7B2%5Cfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5C%5Cfrac%7B%5Cfrac%7B1%7D%7B4%7D%7D%7B%5Cfrac%7B5%7D%7B2%7D%7D%5C%5C%5C%5C%5Cfrac%7B1%5Ctimes2%7D%7B4%5Ctimes5%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7B2%5Ctimes5%7D%5C%5C%5C%5C%5Cfrac%7B1%7D%7B10%7D)
so the ratio is 1:10
The answer would be 3 hope this helps you
