A <span>45 45 90 triangle
so a = b
a^2 + b^2 = </span>c^2<span>
a^2 + a^2 </span>= c^2<span>
2a^2 </span>= c^2<span>
2a^2 </span>= 24^2
<span> 2a^2 = 576
a^2 = 288
a = 12</span>√2
b = a = 12√2
<span>
Area of triangle:
= 1/2 (</span>12√2)(12√2)
<span>= 1/2(288)
= 144
answer
Area = 144 ft^2

Answer: x= y+7 / all over 3
Step-by-step explanation:
y= 3x-7
+7. +7
y+7 =3x
÷3. ÷3
y+7/ 3 = x
Answer:
Step-by-step explanation:
angle CDA = angle ABC (opposite angles of a parallelogram are equal)
56 degree = angle ABC
therefore angle ABC is 56 degree.
Answer:D. 80

Answer: The critical value for a two-tailed t-test = 2.056
The critical value for a one-tailed t-test = 1.706
Step-by-step explanation:
Given : Degree of freedom : df= 26
Significance level : 
Using student's t distribution table , the critical value for a two-tailed t-test will be :-

The critical value for a two-tailed t-test = 2.056
Again, Using student's t distribution table , the critical value for a one-tailed t-test will be :-

The critical value for a one-tailed t-test = 1.706
