Answer:
D. Neither is correct because a 4-sided polygon with at least one pair of parallel sides could be either a parallelogram or a trapezoid.

Step-by-step explanation:
Formula
Area = B * h
Givens
Base = 2.5
height = 5.25
Solution
You choose the value for the base and height from the fact that the height touches the base (which has been extended) at right angles.
Area = 2.5 * 5.25
Area = 13.125
Answer: Area = 13.125 or 13 1/8
Answer:
1) larger number
18 ; 14 ;17 ; 19
2.) smaller number
11, 16, 12, 15
Step-by-step explanation:
Given two numbers in each as follows :
A.) 18 ____ 12 ; 18 > 12
B.) 11 _____14 ; 14 > 11
C.) 15 ____ 17 ; 17 > 15
D.) 19 ____ 11 ; 19 > 11
Color the smaller number ::
20 ____ 11 ; 11 < 20
16 ____ 19 ; 16 < 19
12 ____ 13 ; 12 < 13
15 ____ 20 ; 15 < 20

Answer:
- ∠PAO = 90°
- ∠APO = 30°
- ∠AOB = 120°
- PB ≈ 8.7
Step-by-step explanation:
A tangent makes a right angle with the radius to the point of tangency. Hence ∠PAO is 90°. The ratio of the short side (OA) of the right triangle OAP to the hypotenuse (OP) is 5 : 10 = 1 : 2. These are the ratios found in a 30°-60°-90° triangle, so we know that ∠APO = 30°.
OP is a bisector of angle APB, so that angle is 60°. Angle AOB is the supplement to angle APB, so ∠AOB = 120°.
__
As we said above, triangle OAP is a 30°-60°-90° triangle, so its side lengths have the ratios 1 : √3 : 2. This means PA = PB = 5√3 ≈ 8.7.
