Answer:
96 cm²
Step-by-step explanation:
The area of a rhombus is usually found as half the product of the diagonals. Here, the lengths of the diagonals are 16 cm and 12 cm, so the area is ...
A = (1/2)(d1)(d2) = (1/2)(16 cm)(12 cm) = 96 cm²
_____
This is one of the area formulas it is useful to keep handy.
_____
Here, the area can also be found as 4 times the area of the marked triangle. That triangle's area is ...
A = (1/2)bh = (1/2)(8 cm)(6 cm) = 24 cm²
Four times that area is the are of the rhombus:
rhombus area = 4 × triangle area = 4 × 24 cm² = 96 cm²
Answer:
50 degrees
Step-by-step explanation:
In triangles, the sum of all angles = 180 degrees. So, we can create an equation to solve for x:
- Angle 1 + Angle 2 + Angle 3 = 180 degrees
- (x+15) + (x+28) + 67 = 180
- 2x + 110 = 180
- 2x = 70
- x = 35
We found x, but we're not done. Now, we substitute to find each missing angle:
- Q = x + 28 = (35) + 28 = 63 degrees
- P = x + 15 = (35) + 15 = 50 degrees
Thus, our final answer is: Angle P = 50 degrees.
ANSWER
20 %
EXPLANATION
Let's say B's salary is 100. Given that A's salary is 25% higher than B's salary, then A's salary would be,
To find how many percents is B's salary less than A's, we have to divide the portion of B's salary that is higher than A's, which is 25, by A's salary. And then multiply by 100% to obtain it as a percentage,
Therefore, B's salary is 20% less than A's.
Surface area of a cube is n^2, n being the measurment of any one side of the cube. In this case, 13x13=169, so the answer is 169 mL^2.
