Answer:
B= A = 68
Step-by-step explanation:
ACE = BCD similar triangles. Similar triangles have equal angles.
A=B
C=C
D=E
This means if we can find angle B, we know angle A
BCD is a triangle so it equals 180 degrees
B+C+D = 180
B + 74+38 = 180
Combine like terms
B +112 = 180
Subtract 112 from each side
B +112-112 = 180-112
B = 68
Since we know angle B, we know angle A
B= A = 68
Answer:
33 and 13
Step-by-step explanation:
46/2 = 23
difference is 20, add 10 to one and subtract 10 from 23, giving you two numbers: 13 and 33.
Answer:
22 square feet
Step-by-step explanation:
Area of shaded region = Area of square - Area of circle. The diameter of the circle is also the length of the side of the square as the circumference of the circle is on the circumference of the square.
Area of circle = 3.14 × r × r
r = 10 ÷ 2
= 5
Area of circle = 3.14 × 5 × 5
= 78.5
Area of square = length × length
Area of square = 10 × 10
= 100
Area of shaded region = Square - Circle
= 100 - 78.5
= 21.5
= 22 (to the nearest square foot)
