446x
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The secant- tangent angle 50° is half the difference of the measures of the intercepted arcs, that is
(210 - x) = 50 ( multiply both sides by 2 )
210 - x = 100 ( subtract 210 from both sides )
- x = - 110 ( multiply both sides by - 1 )
x = 110°
The sum of the 3 arcs on the circle = 360°
210 + x + z = 360
210 + 110 + z = 360
320 + z = 360 ( subtract 320 from both sides )
z = 40°
Answer: The height of the model on the right is 22.5 cm .
Step-by-step explanation:
We can see that , the given different models of the same triangular-shaped garden are similar.
For the first model 1 cm = 3.75 m
whereas for the second model 1 cm = 2.5 m
Now , the constant rate of proportion for this (k) =
Now , if height of the model on the left is 15 cm , then the height of the model on right = 15 x k
= 15 x 1.5
= 22.5 cm
Hence, the height of the model on the right is 22.5 cm .
