Given: AB || DC ∠A ≅ ∠D

Prove: ΔABC ≅ ΔDCB

Triangles A B C and D C B share common side C B. Angles C D B and C A B are congruent. Sides C D and A B are parallel.
Isabelle proves that the triangles are congruent by using the parallel lines to determine a second set of angles are congruent. What statement and reason could she have used?

∠ABC ≅ ∠BAC; corresponding angles of parallel lines are congruent.
∠CAB ≅ ∠DCB; alternate interior angles of parallel lines are congruent
∠ABC ≅ ∠DCB; alternate interior angles of parallel lines are congruent
∠ACD ≅ ∠ABD; corresponding angles of parallel lines are congruent.

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

final total: 63
