<span>To solve this question, you must divide the trapezoid into a rectangle and two right triangles. Using the Pythagorean Theorem, you would calculate the height of the triangle which is 4. The dimensions of the rectangle are 5 and 4, hence the area will be 20.</span>
answer may be this so my ans is right xxx
3 upon 75 = 1 /15
13
Step-by-step explanation:
A mean is an average
Formula for Average/Mean:
Total of all categories
(in this case the total scores of the quizzes)
______________________
The number of category
(the number of quizzes so it's 5)
(13 + 19 + 18 + 14 + 1) ÷ 5 = 13
Answer:a=3√7
Step-by-step explanation:
c=12
b=9
a=?
------------------------------
c²=a²+b²
a²=c²-b²
a=√c²-b²
a=√12²-9²
a=√144-81
a=√63
a=3√7
Answer:
196 cm²
Step-by-step explanation:
[Area of Triangle BCD]
A = 
bh = * 28 * 6 = 84 cm²
[Area of Triangle ABD]
A = bh = * 28 * 8 = 112 cm²
