Given:
Consider the below figure attached with this question.
Angles of a triangle are x, y and z.
To find:
The values of x, y and z.
Solution:
If two angles are linear pair, then their sum is 180 degrees.
Similarly,
According the the angle sum property, the sum of all angles of a triangle is 180 degrees.
Divide both sides by -5.
The value of x is 36.
Now,
Therefore, the values of x, y and z are 36, 67 and 77 respectively.
The equation is the given one:
Which is the same as:
And the interval of the angle θ must be (0°,90°) so, 2θ must be (0°,180°).
So the statement is True.
Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
Answer:
3.472
Step-by-step explanation:
The angle of the semtrical cube times the number of 2 because of the number in the area. So the anser is 3.472.
Answer:
Step-by-step explanation:
If one angle = 90 degrees, then the other 2 added together must also = 90.
There is only 1 answer to this, since the triangle is isosceles..
x + x = 90 Combine
2x = 90 Divide by 2
x = 90/2
x = 45
So both acute angles = 45 degrees.
