44°, because the measure of the left side of angle B=112°, 180°-112°=68°, so the measure of the right side of angle B=68°, and since side BE and side CE are congruent and have the same length measurements, then angle C and the right side of angle B are also congruent. All angles of a triangle must add up to 180°, and since you have angle C as 68° and angle B as 68°, 68°+68°= 136°, and 180°-136°=44°
Answer:
A and B
Step-by-step explanation:
Mrs. Quotient asked her students to simplify each of the expressions below. Which of the numbered choices represents the expressions which simplified to the same result? A 126/2 B 23 × 3 C 3 × 21
When simplifying an algebraic expression, the following steps are needed to be taken.
Firstly, remove parenthesis by multiplying the constant with the term in the parenthesis or remove parenthesis using exponent rules for parenthesis in exponent form.
Secondly Combine terms by adding coefficients of terms with the same order and lastly sum all constant.
A) 126/2
Applying the division rule give:
126/2 = 63
B) 23 × 3
Applying multiplication rule gives:
23 × 3 = 69
C) 3 × 21
Applying multiplication rule gives:
3 × 21 = 63
Both the results of expression A and expression B are simplified to the same result
It is an even function since f(-x) = f(x)
