</span><span>the diagonals of a rhombus are perpendicular bisectors of each other
</span>AX<span> = </span>XC<span> = 13. triangle </span>ABX<span> is a right triangle with hypotenuse 14.
</span>
From the pythagoras theorem AB² =<span> AX</span>² + BX²
14² = 13² + BX²
196 = 169 + BX²
27 = BX²----- > BX=√27
BX = 5.20
</span>
The four triangles formed by construction of the diagonals are all congruent since the diagonals are perpendicular bisectors.
Total area of the rhombus is 4 times of ABX triangle
the answer is the option D) 135.1 units ²
Answer:
b
Step-by-step explanation:
Minimum sample size for estimating the population proportion of pine trees over 90 years old in a forest near where you live with <em>margin of error</em> no more than 2% can be calculated using the equation:
n≥ p×(1-p) × where
- n is the sample size
- p is the proportion of pine trees over 90 years old in a forest near where you live
- z is the corresponding z-score for the confidence level
- ME is the margin of error in the estimation (2% or 0.02)
