Answer:
H=21ft
Step-by-step explanation:
Height=2•Area/Base
Area=126ft^2
Base=12ft.
H=2•126/12=21ft
H=21ft
Hope this helps :)
Answer:
56.72mm
Step-by-step explanation:
BQ = 34 - 16 = 18mm
Using similar triangle,
AQ = QC =(16*18)/34 = 8.47mm
AC = 2*8.47 = 16.94 mm
Since
BC = AB = sqrt( AQ² + BQ²)
BC = AB = sqrt( 8.47² + 18²)
BC = AB = 19.89mm
Perimeter of triangle ABC = AB + BC + AC
P = 19.89 + 19.89 + 16.94
Perimeter = 56.72mm

Answer:
B. ΔDEF ≅ ΔSRU
Step-by-step explanation:
Reflection changes corresponding vertices from CCW order to CW order. Vertex D gets reflected to (-6, 4), then translated to (-3, 0). After this transformation, its image is vertex S. The vertices in CW order from S are SRU. Hence, ΔDEF ≅ ΔSRU, matching choice B.
Answer:
9
Step-by-step explanation:
Given
x² - 6x = 5
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 5 + 9, that is
(x - 3)² = 14
