Given: Prove: All right angels are congruent by showing that
What are the missing reasons in the steps of the proof?
A-definition of right angle, definition of congruent, definition of equal, definition of 90 degrees.
B- identity property, reflexive property, substitution property, symmetric property
C- definition of congruent angels, definition of equal angels, substitution property, symmetric property.

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

the answer is z7+8/5
