The area of a trapezoid with base lengths 7 in and 19 in is given by
A = (1/2)(b1 + b2)h
A = (1/2)(7 +19)·7 = 91
The appropriate choice is
D. 91 in²
_____
It can also be figured by adding the area of the 7 in square (49 in²) to the area of the 7×12 in right triangle (42 in²).
Answer:
D) She has a total of $62 in the piggy bank.
Step-by-step explanation:
Jenny has been saving quarters in a piggy bank since she was born.
She decides to add 56 more quarters so that she can buy a $65 phone.
So she has 192 + 56 = 248 quarters currently.
1 quarter is equivalent to $0.25
248 quarters equals;
× $0.25 = $62
So Jenny has a total of $62 in the piggy bank.
Answer:
b = 230 degrees a= 25 degrees
Step-by-step explanation:
d and e are right angles (90 degrees) because when tangent meets radius at circumference a right angle is formed.
c= 180 - 65 - 90 = 25 degrees because angles in a triangle add up to 180
both triangles are congruent as they share the middle line, they have tangents that meet radi(which are equal), and both have right angles. this means that all angles are same in the triangles so a =c =25 and f=65.
65+65=130
360-130 = 230
because angles around a point add up to 360.
b=230
