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:
Solve for x: x + 128 = 180, x = 52°
Solve for y: x + y = 90 or 52 + y = 90, y = 38°
Step-by-step explanation:
In order to solve for the measures of ∠x and ∠y, you first need to remember that angles that are complementary add up to 90° and angles that are supplementary add up to 180°. So, in order to solve for 'x', which is supplementary to a 128° angle, we can set up an equation where the sum of ∠x and 128° = 180°:
x + 128 = 180, subtract 128 from both sides: x + 128 - 128 = 180 - 128, x = 52°
Knowing that ∠x + ∠y = 90° and now that ∠x = 52°, we can set up the second equation:
52 + y = 90, subtract 52 from both sides: 52 + y - 52 = 90 - 52 or y = 38°
Answer:
14y^3 - 10a^2b^2 - 15
Step-by-step explanation:
14y^3 - 5 + 7a^2b^2 - 10 - 17b^2a^2
14y^3 + 7a^2b^2 - 17b^2a^2 - 5 - 10
14y^3 - 10a^2b^2 - 15
