Answer:
∠ b = 23°
Step-by-step explanation:
Complementary angles sum to 90° , then
a + b = 90° , that is
67° + b = 90° ( subtract 67° from both sides )
∠ b = 23°
Answer:
207.19 is the cost on sale
Step-by-step explanation:
If there is a discount of 30%, we still have to pay 100-30 = 70%
295.99 * 70%
295.99 * .70
207.193
Rounding to the nearest cent
207.19 is the cost on sale
Answer:
ok? what am i supposed to do
Step-by-step explanation:
You just have to figure it where you can place 2 solid lines and get 10 triangles ( i can only get 9). Think about the pentagon in the middle of the triangles and see if somehow you can create more triangles using only the two straight lines.
Answer:
18.7 feet far
Step-by-step explanation:
Based on the information given we can conclude that our set up will be a Right triangle (i.e. one angle is 90°), where the hypotenuse will be denoted by the guy wire of 
and angle of 21° is the angle formed between then hypotenuse and the base (i.e. ground).
Thus we want to find the base length (lets call it 
) of this triangle, so we can use trigonometry as we have one angle and the hypotenuse, as follow:
So the base is approximately 18.7 feet far from the tree of the anchored wire.
