It’s the second answer
<1=58 <2=122 <3=58
A quadrilateral always has interior angles that add up to 360 degrees.
Answer:
The missing side length is 3 units long.
Step-by-step explanation:
Use the Pythagorean Theorem where c²=a²+b²,
c=2√3, c²=12
a²=√3, a²=3
Solving for the missing side yields a side length of 3.
Answer:
5y2 + 4y - 12 + 6x
Step-by-step explanation:
3y2 + 2y2 + 8y - 12 + 6x
The total area = 850 sq ft
The sub area of the square = 100 sq ft and the trapezoid = 750 sq ft.
Step-by-step explanation:
Given:
The diagram consist of two figure, a trapezoid ( green border)
To find:
The total area.
Formula
The area of square = side × side sq unit
The area of trapezoid = sum of the parallel sides × height
Now,
The area of square = 10 × 10 sq unit = 100 sq ft
The area of trapezoid = (10 + 20) × 25 sq unit
= 750 sq ft
So, the total area can be given as = 100 + 750 sq ft
= 850 sq ft
