Answer:
X = 33,669.78 ft
Y = 15285.76 ft
Step-by-step explanation:
Given data:
let x be the distance btwn arch and plane
and y be the distance btwn ground point and arch y
we know that


xcos27 = 30000

x = 33,669.78 ft
b) we knwo that


y = tan(27) (30000)
y = 15285.76 ft

Answer: Centimeters
Step By Step: 1 centimeter is equivalent to one hundredth of a meter. 1 millimeter is equivalent to one thousandth of a meter.
Answer:
These two triangles are congruent.
Step-by-step explanation:
You know this bc the markings on the drawing show that Angle B and Angle D are congruent. Also that AB is parallel to CD. This means that Angle BAC and Angle DCA are congruent by ALTERNATE INTERIOR ANGLES. Also, AC is congruent to itself. That makes the two triangles congruent by ANGLE-SIDE-ANGLE.
Now, you need to know that "congruent" triangles (and shapes in general) are the same size and shape. "Similar" triangles (shapes) are the same shape but not necessarily the same size.
