Answer:
x = 15°
Step-by-step explanation:
<em><u>The segment is a diameter, So let us assume the part in which there lies the triangle as a semicircle.</u></em>
=> <em>A triangle inscribed in a semi-circle will always have one of its angle equal to 90</em>
=> <em>So the angle (not 75 and x) is 90 degrees.</em>
<em>=> To find the value of x, we'll subtract rest of the angles from 180 degrees (because the interior angles of a triangle add up to 180°)</em>
<em>So,</em>
=> x = 180-90-75
=> x = 15°
Answer:
5
Step-by-step explanation:
4x-10=2x - Original equation
4x=2x+10 - Move constant to the right-hand side and change its sign
4x-2x=10 - Move variable to the left-hand side and change its sign
2x=10 - Combine like terms and divide both sides by 2
x=5 - Answer
Hope this helps!!!
- Now, we know cos(60°) =
. So put the value there.
Hence LHS = RHS [Proved]
