Ground Mulch
Median: 13.1
Upper Quartile:14.4
Lower Quartile:12.2
Range: 7.4
Answer: 9
Step-by-step explanation: You have to use PEMDAS for this equation. First, E for Exponent. 2 to the 3rd power is 8. Then, M for Multiply. 4 times 2 is 8. You then add the two 8’s together. Finally, S for Subtract. 16-7 is 9
No.
The 3 angles of a triangle need to equal 180 degrees.
The sum of the 3 given angles is greater than 180 ( 160 + 20 + 20 = 200) so it cannot form a triangle.
Answer:
DE = 20units
Step-by-step explanation:
In Δ ABC,
angle A is congruent to angle B.... (given)
therefore, ΔABC is an isoceles triangle.
therefore, CA = CB..... (side opposite to congruent angles are congruent in an isoceles triangle)
therefore, CB = 4 units
In ΔCDE,
angle D is congruent to angle E.... (given)
therefore, ΔCDE is an isoceles triangle.
therefore, CD = CE
therefore, CD = 8 units
ΔCDE ~ ΔCBA
therefore,

What's the problem? I don't see the equation.
