Answer:
Step-by-step explanation:
The diameter cuts the circle into parts that total 180° of arc.
RS +ST = 180°
RS = 180° -ST = 180° -26° = 154°
∠RVS = 154°
__
This value can be used to find x. Equating the angle measures, we have ...
RS = (15x -26)° = 154°
15x = 180 . . . . . divide by °, add 26
x = 180/15 . . . . divide by 15
x = 12
Answer:
Step-by-step explanation:
Left triangle: it has two congruent legs because has an angle of 45 degrees
AB = 
cm
the triangle on the the right is half on an equilateral one
BC = 12 cm
CH = 6√3 cm
AC= (6 + 6√3) cm
2p = 6 + 6√3 + 12 + 6√2 = 18 + 6√3 + 6√2 = 6(3 + √3 + √2) cm
Area = [6(1+√3) * 6]/2 = 18(1+√3) cm^2
Answer:
9² = 40² + 41² - 2(40)(41) cos(C)
81 = 1600 + 1681 - 3280 cos(C)
81 = 3281 - 3280 cos(C)
-3200 = -3280 cos(C)
cos(C) = 3200 / 3280
cos(C) = 40 / 41
Step-by-step explanation:
Answer:
a) Angle X = 108°
<h3>C). Vertically opposite angles</h3>
as AD is parallel to EH both the angles are equal
Where is the question? I have no idea what I need to do to help u?
