Answer:
Angle C = 45 degrees.
Angle D = 30 degrees.
Step-by-step explanation:
Angle C = 45 + 90 = 135 180 - 135 = 45.
Angle D = 180 - 45 = 135 (angle F) 15 + 135 = 150 180 - 150 = 30
Answer:
The measure of
is 30°.
Step-by-step explanation:
In the statement, the angle has been misrepresented. The corrected statement is described below:
<em>"On a unit circle, the terminal point of </em>
<em> is </em>
<em>. What is </em>
<em>?"</em>
The measure of the angle (
), in radians, is in standard form, that is, it is done with respect to the +x semiaxis. The measure of the angle whose terminal point is of the form
is determined by the following inverse trigonometric function:
(1)
If we know that
and
, then the measure of
is:


The measure of
is 30°.
I'm assuming the original equation is

Step 1: Multiply both sides by 2 to eliminate the denominator
Step 2: divide by h
Step 3: subtract a
Answer: £51
Step-by-step explanation:
25% off 49 = 36.75
25% off 19 = 14.25
36.75 + 14.25 = 51
