Answer:
x = 30°
Step-by-step explanation:
< A = 90° {Being vertically opposite angles }
Now
x + 90° + 2x = 180° (Being linear pair)
3x = 180° - 90°
3x = 90°
x = 90° / 3
x = 30°
Hope it will help :)❤
None of your answers are correct
all you have to do it look at what place the value underlined
for example, find value of 5 in 517,849
the 5 is in the 100 thousands place this means that the value is 500,000
We have the formula: sec x = 1 / cos x;
Then, sec (5pi/4) = 1/ cos (5pi/4);
But, cos (5pi/4) = cos (pi + pi/4);
We use the formula: cos (pi + y) = - cosy;
Then, cos (pi + pi/4) = -cos(pi/4) = -
Finally, sec (5pi/4) = -
Answer:
4000
Step-by-step explanation:
<span>a = an angle
x = its supplement
.
a + x = 180 by the definition of the supplement
so
a = 180-x
x = 180-a
.
a = 17x
substitute
17x + x = 180
18x = 180
x = 10
.
a = 17*10
a = 170</span>
