Answer:
264 cm^2
Step-by-step explanation:
Area of a trapezoid = 1/2 (b1+b2) *h
The area of the large trapezoid
b1 = 14 b2 = 25 h = 10+12 = 22
A = 1/2 (14+25) *22 = 429 cm^2
The area of the unshaded trapezoid
b1 = 8 b2 = 25 h = 10
A = 1/2 (8+25) *10 = 165 cm^2
To find the area of the shaded region, take the area of the large trapezoid and subtract the unshaded trapezoid
429 - 165 =264 cm^2
Answer:
x=6
Step-by-step explanation:
In a square, its angles are all 90 degrees. So, cutting a square in half into two triangles from corner to corner produces 45 degree angles on both sides. Since the triangles are now 45-45-90 triangles, we can use the rule where the hypotenuse of the triangle is equal to the square root of 2 times the length of either side. So, the side length is 6.
Answer:
239
Step-by-step explanation:
8 - 4x - m = 5x + 30 - 2
8 - 4x - m = 5x + 28
+4x +4x
8 - m = 9x + 28
-8 -8
-m = 9x + 28
Or if you are finding the value of X
-m = 9x + 28
-28 -28
-m - 28 = 9x
Divide both sides by 9
(-m - 28) = x
9
