Answer:
Since you didn't specify congruency to which angle, I am giving below all angles that are congruent in two groups.
Step-by-step explanation:
Group ONE:
All these angles are congruent <ABE = <BCF = <GBC = < HCD
Group TWO:
All these angles are congruent <EBC = <CFD = <ABG = <BCH
Answer:
Step-by-step explanation:
given that You are visiting a Redwood tree forest and want to verify the height of one of the trees. You measure its shadow along the ground and use trig to calculate the height.
the shadow measures 500 feet and you calculate the angle of elevation to be 35 degrees, This forms a right triangle.
a) Other acute angle is 90-35 = 55 degrees
b) Height of the tree = 500 tan 35 =350.104 feet
c) Here height would be reduced to 350.104 - 5 = 345.104 feet.
Hence distance adjusted= 354.104 cot 35=492.8596 feet.
d) Yes because this is less than 500 feet.
e) height of 5 feet itself is sufficient here
Answer: rotation can be expressed as the composition of two reflections. A composition of reflections over two parallel lines is equivalent to a translation. Example: Given a || b, and pre-image ΔABC, where parallel lines are vertical. The composition of reflections over two intersecting lines is equivalent to a rotation. A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines). i hope this helps.

The oldest cousin should be 10. If their ages are consecutive even whole numbers, then the younger cousins should be 2 & 4. 2+4=6+10=16
