Answer:
11) 153, 85, 238 12) 12, 15, 27
Step-by-step explanation:
To find the area of these shapes, you have to cut them into two seperate shapes as shown the in the image: Shape 1 and Shape 2
11) Let Shape 1 be the rectangle: 17×9=153
let Shape 2 be the triangle: 
×10×8.5=42.5×2=85
Total area: 153 + 85 = 238
12) Let cut this shape vertically where you'll have a rectangle thats 3 by 4 and a rectangle that's 5 by 3
Shape 1: 3×4=12
Shape 2: 5×3=15
Total area: 15 + 12 = 27
Answer:
The Exterior Angle of a Triangle Formula states that the measure of an exterior angle is equal to the sum of its remote interior angles. Therefore, r + 58 = 130 which means r = 72°.

Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
create a proportion: <u> x + 10 </u> = <u> x + x + 10 </u>
5 8
cross-multiply: 8(x + 10) = 5(2x + 10)
8x + 80 = 10x + 50
80 = 2x + 50
30 = 2x
15 = x
For this case we have the following data:
Area of the rectangle, 
Relationship of the sides 5: 3
By definition, the area of a rectangle is given by:
Where
- b: it is the side of least length.
If the sides have a 5: 3 ratio, it means:
Substituting in the formula of the area, we have:
Clearing b:
units
Substituting and clearing:
units
So, the sides are:
units
units
Answer:
units
