80 because of you cross multiply 6 times x and 30 times 16 you get 480 and 6 divided by 480 is 80
6/16=30/?
6x=480
Divided by 6
?=80
Answer:
it is c 21 m2
Step-by-step explanation:
My reason is becuase if you multiply 6 and 1 then you 6 and if you multiply 5 and 3 you get 15 so then you add 15 and 6 and then you get 21 means answer is 21 and M2 hope this helps :)
Answer:
x = 7
Step-by-step explanation:
Similar figures have sides that are proportional. Setting up a proportion for the sides of the figures will help solve for 'x':

Cross-multiply: 3(x + 1) = 6(x - 3)
Distribute: 3x + 3 = 6x - 18
Combine like terms: 21 = 3x
Solve for 'x': x = 7
Angle B is the linear pairs with 60°, so the size is 180-60=120°
Angle ABC is the linear pair with 120°, so the size is 180-120-60°
Angle A corresponds to angle 60°, so they are equal
Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°
Angle ACB is 180-(50+60) = 70°
