Given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°
<h3>What is an Isosceles Triangle?</h3>
The two base angles of any isosceles triangle are always congruent to each other.
Therefore:
m∠CBD = m∠CDB
m∠CBD = 180° - 125° (supplementary angles)
m∠CBD = 55°
Therefore:
m∠CBD = m∠CDB = 55°
In summary, given that ACE is an isosceles triangle, the measure of ∠CDB is: 55°

Answer:
I am willing to help you, Geometry is my best class.
Step-by-step explanation:
For this it would be helpful if you draw a diagram of the situation. You will see that a right triangle can be formed from the problem. We use trigonometric functions to solve. We do as follows:
sin 40 = 50/y
tan 40 = 50/x
Solving we obtain,
x = 60 mi
y = 78 mi
Hope this answers the question. Have a nice day.
A should equal to -3 or -4 depending on whether what the equation is.
For example, if it's (1/9)^(a+1)=81^(a+1) x 27^(2-a), then the answer is -4.
But if it's the other way stated above, then it should be -3.
Hope this helps.
