X^2+6^2=10^2
X^2+36=100
Subtract 36 from both sides
X^2= 64
X=8
Answer:
Area rhombus = 110
Step-by-step explanation:
The diagonals of a rhombus intersect at right angles.
They bisect each other.
So the diagonals form 4 right angle triangles whose legs are 1/2 of each of them.
Leg of 1 triangle = 1/2 * 10 = 5
Other leg of 1 triangle = 1/2 * 22 = 11
Area of 1 triangle = (1/2 ) * 5 * 11 = 1/2 * 55 = 27.5
Area of all 4 triangles = 4 * 27.5
Area of all 4 triangles = 110
Area of rhombus = 110
Answer:
x=10, x=-10
Step-by-step explanation:
8|x| + 6 = 86
8|x| = 86 - 6
8|x| = 80
|x| = 80/8
|x| = 10
∴ x=10, x=-10
Remember that the absolute symbol turns all number inside of it positive, so |-10| = 10 and |10|=10 too.
Answer:
Step-by-step explanation:
The six trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant. This is a first quadrant angle. sine of -17 pi over 3 is equal to square root of 3 over 2, cosine of -17 pi over 3 is equal to 1/2. tan -17 pi over 3 is equal to square root of 3. cosecant-17 pi over 3 is equal to 2/sqrt3, secant of -17 pi over 3 is 2 while cotangent -17 pi over 3 is equal to 1/sqrt 3
