Answer:
250 degrees
Step-by-step explanation:
The arc intercepted by the angle formed by a secant and a tangent is twice the measure of the angle. See the attached image. The intercepted arc measures 110 degrees.
x is the measure of the rest of the circle, so it is 360 - 110 = 250 degrees.
Answer:
equals 22.
Step-by-step explanation:
For every input in a function, there will be one corresponding output. When taking the output of the function and inserting it as the input to the inverse function of the original, the output will be equivalent to the exact input of the original function. In this case, because , that means
will equal 7. Using this knowledge, you can find the value of
, which will be
, so
equals 22.
The height of tree is 32 meter
<em><u>Solution:</u></em>
Given that, The sun is at an angle of elevation of 58 degree
A tree casts a shadow 20 meters long on the ground
The sun, tree and shadow forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AC is the height of tree
AB is the length of shadow
AB = 20 meters
Angle of elevation, angle B = 58 degree
By definition of tan,
In this right angled triangle ABC,
opposite = AC and adjacent = AB
Therefore,
Thus height of tree is 32 meter
