Answer:
a. 72°
b. side DF
Step-by-step explanation:
The base angles of an isosceles triangle are congruent and equal to the complement of half the a.pex angle. The shortest side of the triangle is opposite the smallest angle.
a.∠F = 90° -(36°/2) = 72°
__
b.The smallest angle is 36°. The side opposite that angle is side DF.
_____
Additional comment
The relation we used to find the base angle is based on the fact that the sum of angles in a triangle is 180°. For angle F, with D = F, we have ...
D +F +36° = 180°
2F = 180° -36° . . . . . . substitute D = F, and subtract 36°
F = 90° -(36°/2) . . . . . divide by 2

Answer:
B
Step-by-step explanation:
Time is the independent variable X.
Trees planted is the dependent variable Y.
If its a proportional relationship, then Y = MX should hold.
Lets test our answer according to the table's values.
Y = 65(2) = 130

When Jocelyn runs the 400 meter dash, her finishing times are normally distributed with a mean of 61 seconds and a standard deviation of 2 seconds. Using the empirical rule, what percentage of races will her finishing time be between 57 and 65 seconds?
Answers
Answer:
95% of races will her finishing time be between 57 and 65 seconds.
Step-by-step explanation:
Mean=61 seconds
Standard deviation =2
Empirical rule says,
68% of data covered between mean±1 standard deviation
95% of data covered between mean ±2 standard deviation
99.7% of data covered between mean ± 3 standard deviation.
I'll upload the Empirical rule curve.
Because 57 is 61-2(2) and 65 is 61+2(2), so, 95% of data covered.
So, according to Empirical rule, 95% of races will her finishing time.

Step-by-step explanation:
We are given the base, which is 15 meters. When we increase the base, we will obtain the height, which is 8 meters. Now, let's substitute the base and the height in the formula to find the area of the triangle.
[tex]\rightarrow \dfrac{1}{2} \times 15 \times 8[/tex]
[tex]\rightarrow 15 \times 4[/tex]
[tex]\rightarrow 60 \ \text{m}^{2}[/tex]
Thus, the area of the triangle is [tex]\bold{60 \ \text{m}^{2}}[/tex].

Answer:
a.5/4
Step-by-step explanation:
y equals mx plus c, where m is the gradient(slope of line) & c is the constant
∴y equals (5/4)x-5,where 5/4 represents the "m" & -5 is the constant.
Therefore,5/4 is "m" which is the slope(gradient).
